患者男,57岁,临床诊断冠心病,心房颤动。住院期间口服乙胺碘呋酮转律过程中,于1986年11月24日记录心电图(附图)示:快而匀齐的异位房性P(P’)波,P’率230次/分,室率77次/分。QRS波呈室上性,R-R间距短→长交替,房室传导短R-R为2:1、长R-R为4:1。P’-R逐搏延长(0.20→0.28s),连续3个P’波受阻而结束一个文氏周期。上述特征重复出现。心电图诊断:①阵发性房性心动过速;②交替性文氏型AVB。
Male patient, 57 years old, clinically diagnosed with coronary heart disease, atrial fibrillation. During the period of oral administration of amiodarone during transfusions, the electrocardiogram was recorded on November 24, 1986 (with photos): fast and uniform ectopic atrial P (P ’) wave with a P’ rate of 230 beats / Points, room rate of 77 beats / min. QRS wave was supraventricular, R-R spacing short → long alternating, atrioventricular short R-R is 2: 1, long R-R is 4: 1. P’-R beating stroke extension (0.20 → 0.28s), three consecutive P ’wave blocked and ending a Wen’s cycle. The above features recur. ECG diagnosis: ① paroxysmal atrial tachycardia; ② alternative Venturi AVB.
