摘要:
目的 探讨急性下壁心肌梗死伴房室传导阻滞(AVB)病变过程与冠状 动脉 病变的关系。方法 观察16例急性下壁心肌梗死患者并发AVB的形式和演变过程, 并结合冠状动脉造影进行分析。结果 发生Ⅰ度AVB 1例,Ⅱ度Ⅱ型AVB 3例,Ⅲ度 AVB 12例。房室传导障碍出现的过程多数为Ⅰ度、Ⅱ度Ⅰ型、Ⅱ度Ⅱ型、Ⅲ度AVB,发生时间 64 ±45 h;而恢复过程多数为Ⅲ度、Ⅱ度Ⅱ型、Ⅱ度Ⅰ型、Ⅰ度AVB,恢复时间221±127 h。 AV B发 生期8例中有7例优势型冠状动脉完全阻塞,而AVB恢复期8例中仅2例优势型冠状动脉完全阻塞 (P＜ 0.01)。结论 急性下壁心肌梗死伴房室传导阻滞的产生与恢复是优势型冠状动 脉阻塞与再通的结果。
Abstract:
AIM To study the nature course of atrioventricular block(AVB) and th e relationship between AVB and associated obstruction of coronary artery in acut e inferior wall myocardial infarction. METHODS We observed 16 cases wit h AVB in acute inferior wall myocardial infarction who developed Ⅰ°,Ⅱ° and Ⅲ ° AVB, and analysed their obstruction of coronary artery by angiography. RESUTS There were 1 case with Ⅰ° AVB,3 cases with Ⅱ° AVB, and 12 cases w ith Ⅲ° AVB. The developed course of AVB in most cases was Ⅰ°,Ⅱ° and Ⅲ° AVB;the mean developed time was 64±15 h,and the recovering time was 221±127 h. seven of the 8 cases in acute phase had occlusion in dominant artery,and onl y 2 of the 8 cases in recovered phase had it (P＜0.01). CONCLUSION A cute inferior myocardial infarction complicated by AVB is associated with occlusion of dominant artery.
