心肌梗塞通常累及左心室游离壁及室间隔,右心室游离壁受累者直至近年才有少数临床及病理报告。以下对有关问题作一简介。发病率Isner及Robert分析236例穿壁性心肌梗塞的尸检资料,右心室梗塞占14％,其中97例左室前壁梗塞无1例发生右心室梗塞,而139例左室下壁梗塞者24％并发右心室梗塞。另一组2,000例穿壁性梗塞中左心室梗塞并发右心室梗塞占13.8％。局限于左室下壁的梗塞中,室间隔穿壁性梗塞又是发生右心室梗塞的先决条件。在139例左室下壁梗塞中,74例无室间隔穿壁性梗塞者无1例发生右心室
Myocardial infarction usually involves the left ventricular free wall and ventricular septum, right ventricular free wall involvement until recent years, a small number of clinical and pathological reports. Following a brief introduction on the issue. The incidence of Isner and Robert analysis of 236 cases of transcatheter myocardial infarction autopsy data, right ventricular infarction accounted for 14%, of which 97 cases of left anterior chamber infarction did not occur in 1 case of right ventricular infarction, and 139 cases of left ventricular wall infarction 24 % Concurrent right ventricular infarction. Another group of 2,000 patients with LV infarction complicated by right ventricular infarction accounted for 13.8%. Confined to the infarction of the left ventricular wall, interventricular septal infarction is the prerequisite for the occurrence of right ventricular infarction. In the 139 cases of left ventricular inferior wall infarction, 74 cases of non-ventricular septal infarction without a case of right ventricular
