文献报告，急性下后壁心肌梗死早期出现低血钾者罕见。但此病并发右室梗死时出现低血钾的较为常见，笔者未见国内有关报道。为深入研究其临床意义，我们将临床上所见的47例急性下后壁心肌梗死进行血钾含量测定并分析如下。1对象与方法47例急性下后壁心肌梗死均为1996年1月～199 Literature reports, acute lower posterior wall myocardial infarction early hypokalemia were rare. However, the disease complicated by right ventricular infarction occurs when hypokalemia is more common, I have not seen the domestic reports. To further study its clinical significance, we will be clinically seen in 47 cases of acute posterior myocardial infarction for determination of potassium levels and analyzed as follows. 1 objects and methods 47 cases of acute posterior wall myocardial infarction were January 1996 ~ 199
