【摘要】 目的:探讨急性心肌梗死(AMI)早期发生恶性室性心律失常(室速、室扑、室颤)与低血钾的关系。方法:选择112例AMI患者于发病后24至72小时内测血清钾,根据血钾浓度分为低血钾组(血钾<3.6mmol/L.,44例).及血钾正常组(血钾为3.7-5.5mmol/L,68例),观察、比较两组病人恶性室性心律失常的发生率。结果:低血钾组发生恶性室性心律失常者为38例,占86.3％,血钾正常组发生恶性室性心律失常者为8例.占11.7％,两组间有显著差异(P<0.01)。结论:低血钾是急性心肌梗死早期发生恶性室性心律失常的一个重要危险因素。更多还原

【Abstract】 Objective: To discuss the correlation between severe ventricular arrhythmia occurring in acute myocardial infarction early stage and low serum kalium concentration. Methods: A total of 112 AMI patients were selected. Serum kalium concentration was examined after incidence from 24 hours to 72 hours. According serum kalium level patients were divided into low serum kalium concentration group (serum kalium<3. 6mmol/L. 44 cases) and normal serum kalium concentration group (serum kalium 3- 7-5. 5mmol/L, 68 cases). Then ventricular arrhythmia incidence rates of two groups were compared. Results: Thirty-eight cases took place severe ventricular arrhythmia (36. 3%) in low serum kalium concentration group, 8 cases took place severe ventricular arrhythmia (11. 7%) in normal serum kalium concentration group. There was very significant difference between two groups (F<0. 01). Conclusion: Low serum kalium concentration is an important risk factor for occurring ventricular arrhythmia in AMI early stage.更多还原
