摘要:目的 探讨心脏传导阻滞与心肌梗死部位的关系及对临床预后的影响。 方法 对150例急性心肌梗死(AMI)中合并心脏传导阻滞的57例进行临床分析。 结果 心脏传导阻滞在AMI中的总发生率为38%;与前壁心梗比较，下壁AMI以房室阻滞(AVB)为主;相对于下壁、前壁以束支传导阻滞多见;有心脏传导阻滞者，其住院死亡率、心力衰竭及心源性休克的发生率显著高于无心脏传导阻滞的患者。 结论 心脏传导阻滞的类型与心肌梗死的部位有关，心脏传导阻滞是影响AMI患者近期预后的重要影响因素。

    Abstract:Objective To investigate relationship between cardiac conduction block and location of myocardial infarction and its effect on clinical prognosis in patients with acute myocardial infarction(AMI). Methods Clinical characteristics of57patients with cardiac conduction block were analyzed among the total of150patients with AMI. Results Incidence of cardiac conduction block was38%in patients with AMI.Compared with patients with anterial myocardial infarction ......
