患者女性,35岁,阵发性心悸、胸闷3年。临床诊断:心肌炎。心电图系1991年7月27日描记的Ⅰ、Ⅱ导联同步记录,附图 A 基本节律为窦性,QRS 波可分为3类:(1)R_(2、5、7、10、13)系配对型室性早搏(室早),呈二、二联律出现。(2)R_(1、3、6、8、11、14)QRS 波畸形,起始部见“δ”波,P-R 间期缩短而固定为0.08s,P-J 间期0.20s。此类QRS 波均出现于室早的长代偿间期(1.01—1.06s)后。故推测为慢频率依赖性间歇性 W-P-W Female patient, 35 years old, paroxysmal palpitations, chest tightness for 3 years. Clinical diagnosis: myocarditis. ECG was recorded in July 27, 1991 Ⅰ, Ⅱ lead synchronization records, the basic rhythm of Figure A sinus, QRS wave can be divided into three categories: (1) R_ (2,5,7,10,13) Department of paired ventricular premature beats (room early), was two, two associated law appears. (2) Rf (1,3,6,8,11,14) QRS wave deformity, the beginning of the Department see the “delta” wave, P-R interval is shortened and fixed at 0.08s, P-J interval 0.20s. Such QRS wave appeared in the studio long after the long compensation interval (1.01-1.06s). So it is presumed to be a slow frequency-dependent intermittent W-P-W
