窦-房阻滞及并行心律传出阳滞(EB)较为常见,而其他形式的EB临床上很少见。现报告5例如下。例1 男性,38岁。临床诊断:扩张型心肌病,双结病变。心电图(图1,见第33页,后同)示:室率35—38次/min,P呈逆行性和QRS无关,因以往有房颤、房扑史,故考虑P~-来自心房下部。S_5导联P_2~--P_3~-、
Sinus-atrial block and concurrent rhythm of heartbeat (EB) are more common, while other forms of EB are clinically rare. Now report 5 cases as follows. Example 1 male, 38 years old. Clinical diagnosis: dilated cardiomyopathy, double junction disease. ECG (Figure 1, see page 33, the same below) shows: room rate 35-38 beats / min, P was retrograde and QRS unrelated, in the past with atrial fibrillation, atrial fibrillation history, it is considered P ~ - from the atrium . S_5 lead P_2 ~ --P_3 ~ -,
