目的：探讨急性心肌梗塞早期血钾含量与梗塞部位有无关系，以及急性心肌梗塞早期低血钾与室性心律失常的关系。方法：自１９９４年１月～１９９８年６月，对符合ＷＨＯ诊断标准，确诊为急性心肌梗塞，发病时间在１０小时内的住院患者４９例，在治疗前采静脉血２ｍｌ，即送检。结果：不同梗塞部位组间血钾含量，经统计学处理有显著性差异（Ｐ＜００５），血钾低于３５ｍｍｏｌ／Ｌ的以右室、前壁梗塞为主，血钾低于正常值的病人均伴有室性心律失常。结论：急性心肌梗塞早期应及时补钾，尤其是前壁和右室梗塞，对提高急性心肌梗塞抢救成功率有重要的临床价值。
Objective: To investigate the relationship between the early stage of acute myocardial infarction, the content of potassium and infarction, and the relationship between early hypokalemia and ventricular arrhythmia in acute myocardial infarction. Methods: From January 1994 to June 1998, 49 inpatients diagnosed with acute myocardial infarction who were diagnosed as having acute myocardial infarction within 10 hours were collected, and 2 ml venous blood was collected before treatment. Results: There were significant differences in serum potassium levels between different infarction groups (P <005), with a lower serum potassium level of less than 3.5 mmol / L with right ventricular anterior infarct and low serum potassium Patients with normal values are associated with ventricular arrhythmias. Conclusion: Early acute myocardial infarction should be timely potassium, especially the anterior wall and right ventricular infarction, to improve the success rate of acute myocardial infarction rescue has important clinical value.
