完全性左束支阻滞(CLBBB)多见于高血压、急性前间隔心肌梗塞、主动脉瓣狭窄、心肌病、心肌炎和某些先天性心脏病等;呈间歇性者不多见,一般为频率依赖性。CLBBB因房室文氏传导消失而呈间歇性者更少见。我们最近遇到一例间歇性CLBBB,P-R间期在房室文氏传导延长到临界时先出现LBBB不完全直至完全消失,现报道如下。患者男性,13岁,因发热、咳嗽、流涕2周,胸闷2天,诊断为急性病毒性心肌炎入院,心电图示文氏型房室传导阻滞伴间歇性CLBBB,经静脉滴注氢化考的松200mg/d,二
Complete left bundle branch block (CLBBB) more common in hypertension, acute anterior septal myocardial infarction, aortic stenosis, cardiomyopathy, myocarditis and some congenital heart disease; was intermittent rare, usually the frequency Dependency. CLBBB disappearance of atrioventricular Ventricular conduction was intermittent were even more rare. We recently encountered a case of intermittent CLBBB, P-R interval in the auricle conduction extends to the critical LBBB incomplete until completely disappeared, are reported below. Patients, male, 13 years old, due to fever, cough, runny nose for 2 weeks, chest tightness for 2 days, diagnosed as acute viral myocarditis admitted to the hospital, electrocardiogram showed Venturi-type atrioventricular block with intermittent CLBBB, intravenous infusion of hydrogen test Pine 200mg / d, two
