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。
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 of 57 patients with cardiac conduction block were analyzed among the total of 150 patients with AMI. Results Incidence of cardiac conduction block was 38% in patients with AMI. Comparedwith patients with anterial myocardial infarction, the patients with inferioal myocardial infarction had more atrioventricular block（AVB）. The patients with anterial myocardial infarction had more bundle block than those with inferioal myocardial infarction. The patients with cardiac conduction block had higher incidence of in - hospital mortality, heart failure and cardiogenic shock than those without cardiac conduction block. Conclusion Types of cardiac conduction block were related to location of myocardial infarction, cardiac conduction block was an important factor influencing short - term prognosis of patients with AMI.
