414例急性心肌梗塞患者中并发室内传导阻滞63例(15.21％),左前分支阻滯最常见(9.66％),但其病死率相对较低(15％),其次为右束支传导阻滞(2.17％),病死率则较高(22.22％);左后分支阻滞与右束支传导阻滞+左前分支阻滞+Ⅰ度房室传导阻滞最少(0.24％),其余阻滞为0.72～1.20％。本组室内传导阻滞的病死率为15.17％。与传导正常者相比,无显著差异。似提示:急性心肌梗塞合并室内传导阻滞如不进展为Ⅲ度房室传导阻滞和/或合并泵衰竭及其他严重并发症,其预后未必恶劣。
Among 414 patients with acute myocardial infarction, 63 cases (15.21%) had intra-atrial conduction block and the left anterior branch block was the most common (9.66%), but the mortality was relatively low (15%), followed by right bundle branch block (2.17%), while the case fatality rate was higher (22.22%). The ratio of left posterior branch block to right bundle branch block + left anterior branch block + Ⅰ degree atrioventricular block was the lowest (0.24%), 0.72 ~ 1.20%. This group of indoor block rate of 15.17%. Compared with normal conduction, no significant difference. Cue Tip: Acute myocardial infarction with indwelling house block, if not progress to grade atrioventricular block and / or combined pump failure and other serious complications, the prognosis may not be harsh.
