报道38例急性下壁心肌梗塞（AIMI），合并右室梗塞（RVI）的18例，占474％。右胸导联心电图出现异常Q波、ST段抬高，以V4R、V5R多见。心源性休克、心力衰竭和死亡的发生率，明显高于不合并RVI的AIMI组，而高度房室传导阻滞和其它心律失常两组间无显著差异。提示RVI是AIMI的高危亚组。
Reported 38 cases of acute inferior myocardial infarction (AIMI), right ventricular infarction (RVI) in 18 cases, accounting for 474%. Right chest lead ECG abnormal Q wave, ST segment elevation to V4R, V5R more common. The incidence of cardiogenic shock, heart failure and death was significantly higher in the AIMI group without RVI, whereas there was no significant difference between the two groups in terms of atrioventricular block and other arrhythmias. Tip RVI is a high-risk subgroup of AIMI.
