后壁心肌梗塞时的房室传导障碍常易耐受,一般在2、3天中自行消失,不必应用起搏导管。但有些病例可并发不稳定的房室传导阻滞,有时伴有心室暂停或交界处逸搏节律,当心率慢至每分钟20～30次的临界点时,用起搏导管作心腔内起搏,可明显减低死亡率。为了识别出现房室传导阻滞前的心电图表现,作者分析94例急性后壁心肌梗塞病人的 Posterior wall myocardial infarction, atrioventricular conduction often easy to tolerate, usually disappear in 2,3 days, do not have to use pacing catheter. However, some cases may be complicated by unstable AV block, sometimes accompanied by ventricular pause or rhythm of escape at the junction, when the heart rate slow to 20 to 30 times per minute, the critical point, the use of pacing catheter for intracardiac Stroke can significantly reduce mortality. To identify electrocardiographic findings before atrioventricular block, the authors analyzed 94 patients with acute posterior wall myocardial infarction
