患者男性,48岁,临床诊断:肺心病。1985年3月17日心电图(附图)见:P波呈逆行性,Ⅱ、Ⅲ导联为负波,P’-P’间期0.96—1.00s,心房率60—62次/min。R-R间期节律不匀齐,大多数为0.80s,心室率75/min。此种QRS图形和时限均在正常范围,因其前无相关直立的P波,故为交界性心律(非阵发性心动过速)。逆P’与QRS波群多数无关,表明是发生部位不同的两种交界性心律。部分逆P’在QRS波群之后超
Male patient, 48 years old, clinical diagnosis: Cor Pulmonale. March 17, 1985 ECG (with photos) See: P wave was retrograde, Ⅱ, Ⅲ lead is negative, P’-P ’interval 0.96-1.00s, atrial rate 60-62 times / min. R-R interval rhythm uneven, most of 0.80s, ventricular rate 75 / min. Such QRS graphics and time limits are in the normal range, because of its previous P wave was not related upright, it is borderline rhythm (non-paroxysmal tachycardia). Inverse P ’has nothing to do with the majority of QRS complex, indicating that there are two borderline rhythms of different locations. Partial inverse P ’after QRS complex super
