从300例住院急性心肌梗死中选择左室合并右室梗死36例进行分析。18例梗死早期出现高度房室传导阻滞,48小时内恢复正常房室传导。18例出现泵衰竭,其中12例有右心衰竭体征。10例作冠脉造影,下后壁、右室梗死以右冠脉近端闭塞为主;前壁、右室梗死以左前降支闭塞为主。以STv_2↓/STavF↑比值≤0.5及STⅢ↑/Ⅱ↓比值>1作为急性下壁合并右室梗死的指标,敏感性83.3％～87.5％。防治心律失常、泵衰竭及限制梗死范围是治疗中心环节。
36 cases of left ventricular combined right ventricular infarction were selected from 300 hospitalized acute myocardial infarction. Eighteen patients had a high degree of atrioventricular block in the early stage of infarction and returned to normal atrioventricular conduction within 48 hours. Eighteen cases of pump failure occurred, of which 12 had signs of right heart failure. 10 cases of coronary angiography, the posterior wall, right ventricular infarction with proximal coronary occlusion based; anterior wall, right ventricular infarction with left anterior descending artery occlusion based. The sensitivity of STv_2 ↓ / STavF ↑ ≤0.5 and STⅢ ↑ / Ⅱ ↓ ratio> 1 was 83.3% -87.5% for the acute inferior wall combined with right ventricular infarction. Prevention and treatment of arrhythmia, pump failure and infarction limits the scope of the treatment center.
