The child of heart attack, lead to early pulsate(early fight) is the all the most familiar heart Lyu to disorder.Having no early fight of machine quality heart attack can keep on for several years, the forward prepare good behind.In recent years in the anti- heart the Lyu disorder the clinical application of medicine, it with the result that the heart Lyu disorder of function and other vigilance and values that the seriousness of poisonous side effect causes people gradually.CAST’s( the arrhythmia suppression of the cardiac trial) experimenting a result should consider the performance/risk that the medicine control early fights a ratio after announce.Disordering a medicine treatment to the anti- heart Lyu which early fights should weigh gains or losses and avoid an abuse causing bad result.
1.cause of disease
1)have no obvious machine quality heart attack of the spirit stab to arouse, strain, worry anxiously and tired etc..
2) the machine quality the myocarditis of the heart attack, congenital heart attack, various myocardial diseases, heart valve disease, the Chong guts mental exertion crocks up etc..
3) reason digitalis outside the heart be poisoned, anoxia, sour poisoned, solution the quality mess, anaesthesia, infection etc..
2.the electrocardiogram diagnose
1)the room top early fights
The building early fights(building early)
The ① expects before appear of P wave, appearance is dissimilarity from Dou;
The P-R that the ② most buildings early fight expects a longer than Dou P-R a period and the QRS appearance is normal;
The ③ building don’t be next early to spread to ventricles and the characteristic lead to early take place for the different P wave, can be lap over in T wave and afterward have no QRS wave;
The ④ building early fights behind have another is incompletely generation Chang period.
Hand over boundary to early fight
The ① expects before appear of the P wave can express for:A.the treacherous acts P wave appear before QRSs, the Ⅱ , Ⅲ , aVF leads allied P wave to set upside down, the aVR leads allied P wave erection, the P-R expect<0.10 ses;B.the treacherous acts P wave appear after QRS wave, it R-P period<0.20 ses;C.the QRS waves in front and back and all have no P wave.
The ② has another a companion to have complete generation a Chang a period after hand over the boundary early fight.
2)the room early fights(room early)
The ① expects before appear of the QRS waves, had no related P wave before expect;
The ② expects before appear of the QRS waves appearance generous complicated, QRS wave period many>0.10 ses, QRS wave main wave direction and T wave be contrary;
③ Room early empress many companions have complete generation a Chang a period;
④ Room early sometimes can in order to insert sex, two allied Lyus, three allied Lyus, become to connect the room of hair early or proceed together heart Lyu.
The complexity(complex) room early fights room of point the Pin hair early(the ≥ 6/min), the multiformity room early become to the room early, continuous 3 or above of room early(the room once moved soon) and R-on-T type room early.
3. The room heart Lyu disorder of classification
According to the LOWN surname ratings adjudicate the room early serious degree combine instruction’s cure have already less adopted currently and have another from prepare behind the angle of meaning to the room heart Lyu disorder take in to categorize:
1)the positive room heart Lyu disorder the room heart Lyu that have no the machine quality heart attack’s occurrence disorder, general is room early or short room soon.
2)have already prepare the room heart Lyu of meaning behind disorder have a machine quality a heart attack, performance is room early or have no symptom of short room soon.
3)the malignant room heart Lyu disorder to have a machine quality a heart attack, its heart Lyu disorder for keep on the sex room once moved soon(the room soon keeps on time>30 ses) or the ventricles vibrate.
4. Cure to treat
1) the room top early fights of treatment:Original outbreak and inducement should consider to clean to cause to early fight first, have no symptom room top to early fight, include a short, the building doesn’t soon and not need to be cure.The room top early fight to appear the symptom that can’t bear to be subjected to, or causes a hair room top to once move soon, should consider a medicine treatment.The medicine choice takes orally general Pa Tong, the English thunder west Mao or β -stop.
2) the room early fights of treatment treatment principle:Through an electrocardiogram, Holter monitor(the 24 h dynamic state electrocardiogram monitor), super voice move diagram and exercise to experiment with the chest X line etc. check and combine clinical understanding whether the companion has and early fights related machine quality a heart attack and notice to not and only and early fight Be the machine quality the diagnosis basis of the heart attack(like myocarditis).The inducement specially emphasized to pay attention to clean to result in to fight early, treatment foundation heart attack.The purpose of medicine treatment is early the symptom which eases room to produce, the exaltation suffers from son life quality, the dynamics obstacle of the improvement blood and prevent serious heart Lyu from disorder of risk.
The anti- heart Lyu disorders the orientation certificate that the medicine treatment room early fights
Ⅰ Didn’t need a medicine treatment: The ① has no symptom positive room to early fight(pure sex room early), general have no the machine quality heart attack, room early is single source, eventuality; The ② left room false Jian Suo with the result that room early.
The Ⅱ A doesn’t lay claim to a medicine treatment:Have no machine quality heart attack, the room which has no blood dynamics change early.But have hard accept of aware of self when symptom or complexity room early have already developped into serious heart Lyu to disorder incline to, can consider a medicine treatment.
The Ⅱ B can the medicine cure: The ① has no Pin hair or complexity room of machine quality heart attack to early cause the blood dynamics change; The ② after hasing already prepare the room heart Lyu of meaning disorders:A.room after the Shu of congenital heart attack early;B.the impatient myocarditis companion have various types to early fight;C.the heart lung recover behind or keep on sex room to soon reply room in Lyu early;D.congenital or acquire sex long QT comprehensive advertise for companion room early;E.extend type or fatty and thick type the myocardial disease merger room early;F.two sharp petals take off to hang merger room early;G.digitalis with the result that the Pin deliver and complexity room early.
Ⅲ Has to cure:The malignant room heart Lyu disorder.
The medicine choice companion is hard to accept of aware of self the positive room of symptom early or already develop into serious heart Lyu disorder incline to can consider choosing to use general Pa Tong(the heart Lyu be even), β -stop or western America Lyu.Use the medicine purpose temporarily alleviates symptom, adapt and bear to be subjected to gradually for the convenience of the sufferer, need not take over a long period of time.Digitalis with the result that Pin hair or complexity room early and the Shu of congenital heart attack take place behind of the room can early choose the benzene secure English sodium or western America Lyu.It as to it’s have already prepare the room heart Lyu of meaning to disorder behind, can choose to use β -stop, may also careful choose to use An iodine Tong.The malignant room heart Lyu disorders to choose to use intravenous injection benefit many cards because of or An iodine Tong.The clinical data hint unite application the An iodine Tong and β -stop may raise curative effect, lower an ill rate.
Pay attention to with visit, periodical 24 h electrocardiogram and super voice move the diagram check monitor condition variety
