目的 :探讨急性心肌梗死并发房室传导阻滞的临床意义。方法 :分析 44 4例急性心肌梗死并 3 7例房室传导阻滞的临床资料。结果 :160例下后壁心肌梗死 ,发生房室传导阻滞 2 8例 ,发生率 17 5 %,死亡 6例 ,死亡率 2 1%;2 84例前壁心肌梗死发生房室传导阻滞 9例 ,发生率 3 17%,死亡 8例 ,死亡率 89%(P均 <0 .0 0 5 )。结论 :下后壁心肌梗死易并发房室传导阻滞预后好 ,前壁心肌梗死并房室传导阻滞预后差
Objective: To investigate the clinical significance of atrioventricular block in patients with acute myocardial infarction. Methods: 444 cases of acute myocardial infarction and 37 cases of atrioventricular block clinical data were analyzed. Results: 160 cases of posterior wall myocardial infarction, atrioventricular block occurred in 28 cases, the incidence of 17 5%, 6 deaths, the mortality rate was 21%; 2 84 cases of anterior myocardial infarction with atrioventricular block 9 Cases, the incidence of 3 17%, 8 fatal cases, the mortality rate was 89% (P <0.05). Conclusion: The posterior wall myocardial infarction complicated by atrioventricular block has a good prognosis, anterior wall myocardial infarction with poor prognosis of atrioventricular block
