摘要：目的 探讨急性下壁心肌梗死时发生房室传导阻滞的时间与病情发展的关系。方法 对162例下壁心梗患者的临床心电图资料和32例冠脉造影资料进行分析。根据心电图表现将其分成超急性期、演变期和恢复期组。结果 有59例患者在不同时期发生不同程度的房室传导阻滞，其中超急性期发生30例(50.8%)，其房室传导阻滞的程度和临床严重并发症发生数均高于演变期和恢复期组，P<0.05。后二期多表现为Ⅰ度房室传导阻滞，P<0.05。结论 下壁心梗早期发生房室传导阻滞多标志病情严重，阻滞程度较高，心梗面积较大。

Abstract Objective Approach the relationship ofoccuring time of atrioventricular block(AVB)and clinic in acute inferior wall myocardialinfarction.Method The electrocardiographic data of 162 patients and 32cases angiograohic data were analysed.The clinic course were classified into super acutephase,evolve phase and recover phase based on electrocardiography.Results Therewere 59 cases had different degree AVB in different phase.lt was 30 cases(50.8%) AVBoccuring during super acute phase,and the degree AVB and clinic complication were moreseriously then occured in evolve and recover phase,P<0.05.lt was more cases of I AVB inlate two phase.Conclusions The AVB occured during early phase ofinferior AMl were being a index that with a high degree AVB,large size infarction and aserious clinic course.
