目的 :探讨不同部位的急性心肌梗塞溶栓后冠状动脉再灌注致心律失常的类型、原因、机理、死亡率。方法 :对 5 8例急性心肌梗塞溶栓后再灌注心律失常出现情况进行分析。结果 :急性心肌梗塞溶栓后出现心律失常的占 83 % ,类型以室性心律失常为主 ,死亡率为 2 0 .8% ,死亡原因多为室速伴室颤或室性自搏心律、Ⅲ° -AVB。结论 :急性心肌梗塞溶栓后再灌注损伤与心肌M细胞的损伤是造成溶栓后异位激动形成的重要机制 ,进一步探讨再灌注心律失常形成机理 ,采取积极的干预措施是减少急性心肌梗塞死亡率的关键
Objective: To investigate the types, causes, mechanism and mortality of coronary arrhythmia caused by coronary artery thrombolysis after acute myocardial infarction in different parts. Methods: Fifty-eight cases of acute myocardial infarction after thrombolytic reperfusion arrhythmia were analyzed. Results: 83% of patients with arrhythmia after thrombolysis of acute myocardial infarction were type ventricular arrhythmias, with a mortality rate of 20.8%. Most of the causes of death were ventricular tachycardia with ventricular fibrillation or ventricular stroke, III ° -AVB. Conclusion: The reperfusion injury and myocardial M cell injury after thrombolysis in acute myocardial infarction are the important mechanisms leading to the formation of ectopic activation after thrombolysis. To further investigate the mechanism of reperfusion arrhythmia, take a positive intervention to reduce the death of acute myocardial infarction Rate the key
