房室传导反向文氏现象(reversed Wenckebach phenomenon)是一种少见的心电图现象,见于房室传导阻滞和早搏后心动周期。最近我们遇到1例,报道如下: 患者男性,24岁,因头晕、心悸、乏力3天入院。起病前1周有上感史。平素健康。体检心律不规则,早搏20次/分,心各脏瓣膜区未闻及器质性杂音。实验室CPK、LDH、GOT及ESR均属正常范围。超声心动图各房室大小正常,未见二尖瓣脱垂表现。临床诊断:病毒性心肌炎,室性并行收缩性心动过速伴不规则传出阻滞。附图(见第169页)为模拟V_5导联记 Atrioventricular conduction Reversing Wenckebach phenomenon is a rare ECG phenomenon found in atrioventricular block and premature beat cardiac cycles. Recently we encountered 1 case, reported as follows: Male patient, 24 years old, dizzy, palpitations, fatigue 3 days admission. A week before the onset of a sense of history. Usually healthy. Physical examination irregular heartbeat, premature beats 20 beats / min, heart valve area has not heard of organic noise. Laboratory CPK, LDH, GOT and ESR are within the normal range. Echocardiography atrioventricular normal size, no mitral valve prolapse performance. Clinical diagnosis: viral myocarditis, ventricular tachycardia with irregular parallel block.
