Heart early Bo

Heart early Bo brief introductionWhat is to early fight, what are mechanism and common electrocardiogram characteristic of its occurrence ? Sometimes 1 or several differents which appear in advance happen to pulsate in the pulsate of heart the process, once was called to early pulsate, and then was called to expect ex- constringency, the brief name early fights.Early fighting is that the actively sexual different pulsate, is more familiar heart Lyu to disorder of a.The reason which causes to early fight includes a lot and the heart which has some healthy persons may also take place to early fight, but alter occurrence in the abnormal state heart.The healthy person takes place to fight usually early to have some artificial inducements, such as motion concussion, make a meal of, lead Lao, upper respiratory infection, Dan way the disease, electrolyte mess, medicine function...etc. of the system.Lead to early pulsate about 40% occurrence at the cardiovascular disease, easy the occurrence early fights of the heart disease has a coronary, high blood pressure heart attack, rheumatism a heart attack two the sharp petals be narrow, the lung source heart attack, myocarditis, myocardial disease, heart wrap burning etc..Other diseases which cause to early fight have a thyroid gland function decrease, anemic and low blood potassium etc..Various to the stimulating factor of hearts, such as heart pipe check, because of to heart wall of direct incitement, can appear building or room to early fight;Excessively make an effort in the heart pipe check process, or lead to quickly sample blood specimen, or add to press to inject to build shadow etc. inside quickly centripetal and dirty chamber, can once take place to early pulsate.Heart surgical operation press heart to press, lead long to pull perhaps carry on valve separation and install cardiac pacemakers can once produce to early pulsate, these stimulate factor once cancellation, early fight and then can disappear.Applied some medicine can once cause as well to early pulsate, particularly digitalis medicine, other like caffeine, different C adrenaline etc., stopping using these medicines to early fight can disappear.
Three kinds of standpointsCurrently, the concerning the mechanism which early fights occurrence includes three kinds of standpoints:A kind of ories think is myocardial of partial exist an excitement to increase Gao of different fight a point, this different fights a point, at some sow the cause under the induct of vegetable, actively take place concussion, make atrium or ventricles the occurrence pulsates in advance;Another theories think is because fold to return, namely when the bottom of the Dou sexual impulse spread, a part of myocardials are placed in opposite shouldn't expect, but when the myocardial concussion of rest part complete, concussion again spread to this part of myocardials, can make this part of myocardials produce once to pulsate in advance;Still there is a kind of standpoint think:In the myocardial, especially at ventricles muscle memory active in one of, have different of certain stanza Lyu to fight a point.The common electrocardiogram characteristics which early fights is appear in advance of the single or two different stanza Lyu of electricity concussion, often appear a Chang because of the normal heart Lyu of the interference next period intermittent, the minority is to insert the sexual.Can factitiously is divided into occasional to early fight and much deliver to early fight according to the frequency that it appear, the Pin hair early fights.Some Pins deliver of early fight can appear to certainly form couples regulation, such as two allied Lyu, three allied Lyu;If the early fought successively appeared in time up exist a certain multiple relation, but with normal the of stanza Lyu then has no fixed of accidentally allied time relate to, this kind early fight can appear is move a period of any part, as a result can produce building or the room fusion wave.

What is meant by expecting ex- constringency
Expect the ex- constringency to also call to pulsate before the period, call to early fight and early jump.It is a kind of most familiar heart Lyu to disorder.The elfevident is a kind of heart palpitates that the foundation in normal heart Lyu is last to send out in advance. Because expect ex- constringency is in the Dou or different the foundation of the heart Lyu up, the heart conducts system of a certain send out concussion in advance, lead early cause heart of a part of or all take place once in addition to pole.This is a little bit exciting can rare surname-Pu gold wild surname system in atrium, the building room conjunction area, ventricles, even knot in the Dou building.Therefore can be called building, the building room conjunction area, room or Dou to expect ex- constringency respectively. Early fighting is very familiar and anyone all unavoidably doesn't take place in the whole life.Generally speaking, the age is the younger the more rare and the age is old to much see more more.It the tallest incidence rate lie in 50-70 years old of.The 5% or so healthy person can once take place to early pulsate. While early fighting if touch a pulse, will discover the pulse leaves out once but physically is a heart to jump once in advance and have 1 later on grow of intermittent.The heart palpitates of advance is a heart constringency over early inside heart chamber the blood quantity of the Chong Ying decrease, pump blood within aorta, the quantity also reduce, can't spread to vein wave surroundings artery to cause a pulse, so become the pulse shed off, this be also the Chinese medicine diagnoses vein appear of"knot generation vein".
Can early fighting influence a health?In the clinical work, usually someone ask:Can "early fight" influence a health?The  front has been already talk over and the heartbeat is subjected to Dou building knot conductor.At normally under the circumstance, the Dou building knot send out of regulation impulse, through heart of the conduction system spread to the atrium and the ventricles and arouse the whole heartbeat thus.Because a certain reason makes inside atrium or the excitement of some one part of myocardials in the ventricles lead high, perhaps because of conduct system occurrence break down, at this time can make in the normal stanza Lyu burst upon advance excitement and constringency, this kind of circumstance is to early fight, and then once be called to early pulsate or expect ex- constringency and expect outside constringency.According to early fight the part dissimilarity of origins, can is divided into building, building room to hand over boundary and room to early fight 3 kinds.Most is the room early fight, secondly is a building to early fight and at least what to see hand over boundary to early fight.Early fighting is the most familiar heart Lyu to disorder of a.Someone reports in the normal crowd of have no symptom, observe dynamic state electrocardiogram continuously for 24 hours, can appear 50% people to early fight;Observe continuously for 48 hours, then have 70% ～s 80% people to appear to early fight.Usually under the circumstance, heart beating, oneself is a felling not arrive of.When the occurrence early fights, because of the ventricles strong dint constringency, can feel heart beating;Again because of early fight behind there is a deadlock cleft, past again can have the felling of heart palpitates deadlock.The everyone feels inconsistent and have of say that being a heart concussed once, the felling heart desire for have is from the throat in jump out, have of is obviously confused and unwell.In addition, can also the companion contain unwell stuffy, disgusted chest, a cough, dizziness...etc..The person who also has even takes place to multifariously and early fight, can milli- insensibility and symptom, only at the doctor listen to diagnose or electrocardiogram check just disheveled hair now.The heart is tidy, the flutter of rule, mainly is fight issue of blood liquid satisfy whole body organization organ of demand.Taking place to early fight is a room to early fight, can make the heart fight amount of decrease.But, every minute little in 6 time early fight, almost has no influence to the healthy body.The occasional building early fights, the coronary artery blood reduce the quantity be only for 5%, the occasional room early fights to reduce 12%, and both all has no influence to the brain circulation.More than 6 time Pin hairs early fight every minute, the circumstance is different, it can reduce the coronary artery amount of blood to reach to 25% or so, the decrease brain circulation blood measures 8% ～s 12%, reduce kidney circulation a blood to measure 8% ～s 10%, so will bring certain influence to the health.But, the key lies in having no machine quality cardiovascular disease, if have a serious heart attack, so Pin hair's early fighting will cause the myocardial lack blood, angina pectoris or mental exertion to crock up.The Pin hair building fights often early to take place the signal of atrium quiver for the heart patient, the Pin hair room early fight and can develop into the room once move soon, even the ventricles vibrate but die abruptly.If have no serious heart attack, even early fight Pin hair and also be unlikely to result in serious result.Clinical up, function namely the physiology early fights even familiar.Normal person at lead Lao, strain, concussion, worry anxiously uneasy, or at a great deal of smoking, drink alcohol, drink coffee, drink strong tea all can take place to early fight, can also at take a rest or lie bed sleep occurrence;The old people can take place after be constipated.This kind of function early fights to then disappear after inducting reason to clean and make to go deep into completely to the occurrence of check, also have no the proof of heart attack it is thus clear that.Some health appear several after early fighting, thought top very nervous with fear, so on the contrary urge to early fight to increase.The pathology early fights also not a few see.It is under heart attack or other pathologic circumstances of the various machine quality, is if have fever, anemic, thyroid gland function Kang enter, rheumatism activity, high blood pressure, low blood potassium, serious anoxia or some medicine poisoned hour take place. Can say, this kind of early fighting to appear is an important signal that the myocardial lacks blood and hurts.For example the patient of the myocardial infarction of coronary take place to early fight to often hint that having a serious myocardial lacks blood;The breeze secret concern patient early fights to often hint that the heart function isn't whole;High blood pressure heart the patient fights often early fatty with ventricles muscle big and Lao Sun relevant.Total of to speak, old man and child appear to fight often early to is quality for machine.If early fight appear angina pectoris or mental exertion to crock up, then affirm is that the machine is quality.Every have spirit nasty or heart extension etc. heart attack performance, or have a coronary to easily deliver the person of factor(high blood pressure, Gao Xie3 Zhi, diabetes, fat, household history etc.) to appear to early fight, much is the machine quality.The machine quality early fights to healthily have the degree the different influence, should under the doctor's instruction in time but reasonable treatment.
What are clinical performance and electrocardiogram characteristic that the building early fights ? The building early fights most to see at the normal person, usually don't cause to aware of self symptom, can't cause circulation obstacle, either, sometimes the patient can tell heart palpitates, chest stuffy.Tired, worry anxiously, smoke cigarette, drink alcohol, drink strong tea, drink coffee, digitalis poisoned, the atrium pathological changes, mental exertion crock up and myocardial's lacking blood and myocardial infarction all can cause building early.The building that the different disease cause can early appear different chaperonage symptom, the heart listens to diagnose audibility to heart to pulsate suddenly appear in advance, and then is the generation of the extension the Chang be intermittent and early fight the first heart a sound is more normally loud and clear, the disloyalty of heart sound be weak or out of hearing and early fight of the pulse be weak, or could not touch.Its electrocardiogram characteristic has the following what time:(1)The wave of P ′ appeared in advance.(the wave of P ′ can be lap over in ex- Dou pulsate of T wave in)(2)The P ′ R the period be normal or light the degree prolong.(3)P ′ wave appearance and the wave of Dou P be different.(4)The QRS waves after the P ′ can normally or abnormal.If have abnormal the QRS wave then is called building to early fight the companion indoor difference to conduct.If the P wave has no QRS wave, be called don't next spread building early.At same lead allied up, if the appearance of P ′ and form couples a period dissimilarity, be called many source building early.(5)Often there is imperfect generation Chang being intermittent, then include building as early as inside of two time of of normal P waves be short to be apart from at the double and normal PP.
What are clinical performance and electrocardiogram characteristic that the room early fights ? BE order by the different stanza Lyu of the whichever part in the ventricles or the room partition to send out electricity impulse to cause ventricles in advance before the Dou building knot impulse haven't arrived ventricles of in addition to pole, be called room to expect ex- constringency, call room early.In normally the crowd, the room can early induct because of general factor, for example smoke cigarette, drink strong tea, drink alcohol, feeling tense, excessiveness tired, indigestion, blood potassium lead low, thyroid gland function Kang enter, take some medicine etc.s, have of even check not to take up a post what reason.In the machine quality the heart attack, it is the most familiar to take off to hang at the coronary, rheumatism heart attack, high blood pressure heart attack, myocarditis, myocardial disease and two sharp petals etc..Room's early fighting is a kind of familiar heart Lyu to disorder and the patient often tells to say that the heart palpitates, chest contains "bump shot".The majority can immediately do to visit patients at home to break when the heart listen to diagnose and early fight the first heart sound more and normally and the first heart a stereo set is bright, the disloyalty of heart sound be weak, perhaps out of hearing, these characteristics and building early fight a homology, but room early generation after fight the Chang be intermittent time be longer and belong to complete generation Chang intermittent.If the room early multifarious occurrence, sometimes not easy vibrate differentiation with atrium, can let patient's activity, if physical strength activity after, the patient heart rate speed, but the stanza Lyu tend after rule, room then early fighting of possibility compare bigly, because human body activity, Dou frequency increment, overcame a different the manifestation of the heart Lyu.If the normal heart all early fights with a room after fight each time, then become two allied Lyu, is see in digitalis more poisoned, isn't that the digitalis is poisoned causable of two allied Lyu, often hint the machine quality heart attack.Room early fight is see in normal person more, judge the room early property, have to synthesize analysis, if early fight is cause by smoke, wine...etc. some inducements, much belong to function, don't generally and not need to be cure.Become to the machine quality sexually transmitted disease the causable room early give according to the patient's concrete circumstance treatment.The electrocardiogram that the room early fights has the following what time:(1)Appear in advance of generous of the QRS waves, the QRS wave expects more than 0.11 and it has never led early P wave to appear ago.(2)The P wave can appear in the ST segment top or cover up in the QRS, T wave, R-P time often in 0.12~0.20, P wave with advance of the QRS wave be irrelevant.(3)ST segment and T wave direction often with QRS wave the direction be contrary.(4)Usually there is completeness generation Chang being intermittent.(namely and early fight in front and back two Dou the heart fight to be separated of time for normally move a period of 200%)(5)Sometimes the room early clips in two continuous Dous to pulsate of, be called an or insert sex room to early fight.(6)Sometimes become two allied Lyus, three allied Lyu, or the room early fight to become a short room soon.(7)At same lead allied up, it is thus clear that many source rooms early fight, the room early fights of appearance dissimilarity.
How judge the room early dangerous degree?The general room early fights certainly lifeless dangerous, don't excessively worry.But sometimes the room of Pin hair early fights, particularly is the R wave of wave to early fall fore a T wave for pulsate up, namely RonT, at this time will take place room to once move soon, even develop to vibrate into the ventricles, will endanger life.Early fight to the room, the Lown ′ s is divided into its some Classeses, the risk of the Class more high abrupt death is more big, special have certain reference value to the patient of impatient myocardial infarction.The ratings of American Lown is as follows:0 classes:Have no room to early fight.Ⅰ Class:The room early fights<30>30 times/hour.Ⅲ Class:The multiformity room early fights.The Ⅳ a class:Become to(become allied Lyu) early fight.The Ⅳ b class:The room once moves soon.Ⅴ Class: R wave the room which falls on the T wave(Ron T) early fights.There are many research detections recently, the room early fights of the number increase with the growth of age.Think the Lown ′ s ratings most experts, that ratings only suiteds for the room heart Lyu that the patient of myocardial infarction take place to disorder.This mainly is because a part of healthy persons win often can check a room of Ron T to early fight, but none example Cu hair the room once moved soon, room Zhan.And the phenomenon of Ron T can appear in gearing the patient electrocardiogram which fight a machine, haven't discover can the Cu hair room once moved soon or room Zhan.Currently, more and more of main basis research express, judge room to early fight a risk, the following what time:(1)Foundation heart pathological changes, such as the serious myocardial infarction, the blood, myocarditis or room wall of the lack of severity lump wait;(2)Heart function appearance;(3)Electrolyte whether mess.Heart function the appearance be good and the room which has no the patient of machine quality heart attack early fights to generally belong to positive heart Lyu to disorder.There is serious machine quality heart attack, heart function obviously damaged patient, such as room early the ≥Ⅲ class, then think is a risk Gao, already die abruptly possible heart Lyu disorder.
Does the patient of the empress of myocardial infarction take place room to early fight how to do? The traditional idea think that myocardial infarction empress of patient such as occurrence the room early fight, then probably the Cu deliver the room heart Lyu of fatal disorder, such as the room once moved soon, ventricles vibrate.The room early fights to actually have influence behind after the impatient myocardial infarction to the prepare of patient, there is much influence and study enunciation in recent years:Has no the room of symptom to early fight behind to the myocardial infarction, carry on anti- heart Lyu to disorder a treatment, although the room has already fought to get a valid control, also can't prevent patient from the heart source the occurrence of abrupt death.Much lay claim to in the world currently: (1)If the patient take place of the room early fights to have no symptom, in the meantime heart Lyu disorder to prepare behind have no influence of, to these patient's heart Lyu disorder need not handle.(2)If have room to early fight, the patient has no symptom, but the heart Lyu have influence after disorder the rightness prepare of, reply a basic cause of disease treatment first to these patients, rectify mental exertion to crock up, handle to be taken bad at first.Can adopt some medicine that the anti- heart Lyus disorder, such as the β Zu Zhi.(3)Have room early and there is symptom, but the heart Lyu have no influence after disorder the rightness prepare of, if is a youth person, can carry on surgical operation or eliminate to melt Shu; Lack a guts patient of heart attack relapse or aggravate towards having symptom but have no, choose to use anti- heart Lyu to disorder a medicine in response to the circumspect, in order to prevent medicine with the result that heartThe Lyu disorders a function, or brings other side effect but makes condition worsen.(4)If the room of occurrence early has symptom, and early fights to prepare to have influence behind of, should give heart electricity procedure stimulate, carry on anti- heart Lyu disorder medicine sieving.If after using a medicine, the single form keeps on sex room to be no longer given or get an electric shock procedure to stimulate soon induct, explain that medicine is valid.Apply that medicine, can lower a patient to take place the heart source the opportunity of the abrupt death.But also someone lay claim to adoption surgical operation or eliminate to melt Shu excision or break a focus that become heart Lyu's disorder for can't accept the patient of these treatment measures, can transplant anti- heart Lyu to disorder of rise fight a machine.
How treat function room early?The room of detection early fights in clinically, if have no proof certificate it to have heart abnormality and the cause of disease out of the heart, call that this kind of heart Lyu disorders for the function room early.In a brief be the room that the normal person can appear early, it belongs to positive heart Lyu to disorder.In the normal crowd, function room early of the incidence rate is 70%s at 50% ～s.The  wants to make sure that the room is early function, first in response to excepted various machine quality heart attack, should choose an appropriate check, include the experiment, ventricles night electric potential, heart B of the check-up, electrocardiogram, dynamic state electrocardiogram, sport super, heart pit vegetable check, have special demand, can adopt the heart electricity physiology check and hat vein and ventricles to build shadow to wait means.Secondly;Still want excepted can induct the room early inducement, like electrolyte mess, the medicine other system diseases of the influence, A Kang...etc..Moreover is analytical the judgment room early Class, often adopt American standard ratings of the Lown ratings.But most experts think currently, Lown ratings standard, the limit useds for the machine quality the sufferer of the heart attack, opposite to normal person to say that the meaning isn't big.Arrive to still could not lift one currently reasonable of in keeping with normal person's room early electrocardiogram ratings standard.To the function room early, the person, who have, can have no nerve, the person but worry anxiously, who have, is uneasy, be rattled, entertain foolish ideas, by all meansly seek a doctor to open some medicine that the anti- heart Lyus disorder.Some clinical doctors mix function room the machine quality room early and together early, exaggerative it bane, open some control rooms effect to the patient early is better, but side effect also bigger 2 and 3 line medicines.The blindness pursues to early fight to disappear but persistently enlarges the medicine amount of or consociation to use a medicine.The above-mentioned way of doing fraud is big at the benefit, increased the sufferer's mental stress and resulted in anti- heart the Lyu disorder the abuse of medicine and make application anti- heart the Lyu disorder a medicine with the result that the heart Lyu disorder of the case increase.Function room the sufferer early doesn't do a treatment in principle, if have obvious symptom, proper choose to use a tranquilizer, reduce in the meantime bad stimulate(if quit smoking, little take tea or coffee), can also use the small β Zu Zhi for measure, such as doubly he the joy gram, ammonia Mao feel at ease etc. medicine treatment.
Does the room early fight to all need to be cure, which rooms early fight to need to be cure, how cure? Room's early fighting is a kind of most familiar heart Lyu to disorder and the normal person and various heart attack all can take place room early.The room early fights whether need to be cure, mainly be decided by a cause of disease.If is an occurrence in normal person, usually because of motion concussion, spirit strain, excesssive of fatigue, have impaired digestion, smoke cigarette, drink strong tea or drink coffee induct, if have no obvious symptom, need not use a medicine treatment.Such as patient's symptom obvious, the treatment should take removing symptom as a purpose.Ease the patient's worry and discomfort, avoid inducting a factor, such as smoke cigarette, coffee, should arouse etc..The medicine should choose to use the β Zu Zhi or western America Lyu and as far as possible avoid application Ⅰ C, the Ⅲ anti- heart Lyu to disorder medicine. The machine quality heart attack causes room to early fight familiar take off with two sharp petals to hang a patient at the coronary, myocardial disease, rheumatism heart attack.If the electrocardiogram up appears a following circumstance, much hint that the room early fights to is rational for disease:① Many source rooms early fight.The ② become to or the room of continuous emergence early fight.The ③ room is early appear in ex- heart fight of T wave up(namely RonT phenomenon), the allied Lyu expects less than 0.40.Three kinds of above circumstances often easily inducted room to once move soon or room Zhan, have to handle in time.④ Especially the breadth type room early fights and the QRS period ≥ is 0.6.⑤ Especially the short type room early fights, namely each lead allied medium the room early fight abnormality QRS waves to flap a≤ 1.0 mVs.The ⑥ room early fight the QRS waves have already shown Zhao to slice a vestige, the ascension pays or descends to pay an anomaly.The T wave that the ⑦ room early fights is sharp, twos are symmetry, T wave the main wave of the direction and the wave of QR S the direction be consistent and the ST segment presents a level type a change.The ⑧ proceeds together heart Lyu a type the room early fights.The ⑨ early fights index number small in 1.The μ appears in having the sketch that the myocardial lacks blood or myocardial infarction of the room early fights. The treatment that the pathologic sex room early fights wants to aim at a cause of disease treatment first and fight usually early along with amendment but decrease of the foundation paroxysm or the disappearance.If the symptom is obvious, can choose to use the following medicine treatment: ① Benefit many cards because of, the card of Pu Lu is because of the Mao An, bromine Xia An, to the room early fight more and effectively.The companion of especially impatient myocardial infarction has room to early fight. ②β -BE fight by the secure English sodium, the D of Kui Ni, difference of the body Zu Zhi, benzene to settle etc., to various early fight all and effectively.The one who have bronchus asthma should not use the β Zu Zhi. The ③ one who move to early fight over the slow companion, can give give an article treatment. The ④ digitalis medicine:To the mental exertion crock up to causablely and early fight effectively.Poisoned to digitalis cause of early fight, in addition to stopping using digitalis medicine, give secure English sodium etc. of the chlorination potassium, benzene can acquire a control. The patient of the empress or myocardial disease of the ⑤ myocardial infarction erupts room early, the heart abrupt death incidence rate is higher, especially be to exist left room to shoot a blood score to obviously lower in the meantime, heart abrupt death of the risk will consumedly increase.Applied some nti- heart Lyu disorder medicine treatment after the myocardial infarction room early, abrupt death and cardiovascular total death rate on the contrary show Zhao increment.The reason is these anti- heart the Lyu disorder medicine to have with the result that the heart Lyu disorders a function.Therefore, room after should avoid using the treatment myocardial infarction of the Ⅰ medicine early.Although the β Zu Zhi don't show Zhao to the room early curative effect, can lower myocardial infarction to die abruptly an incidence rate behind.The An iodine Tong is soon early very valid to repress room, but should notice possible occurrence to turn round sex room to once move.
