为了分析老年急性心肌梗塞（ＡＭＩ）２周后发生心原性猝死的原因，本文总结了１２例心原性猝死患者，其中６例进行了尸检。认为无论是持续心肌电不稳定所致的原发性室颤，还是梗塞早期的合并症，如体克、心功能不全，梗塞后心绞痛引起的继发性室颤均为晚发心原性猝死的常见原因。尸检结果表明，老年ＡＭＩ晚发心原性猝死多发生于冠脉病变严重者。对于室颤高危患者应采取积极预防措施，如抗心律失常药物的合理应用、改善冠脉循环及改善心脏功能，避免诱发因素，可以减少猝死的发生。
In order to analyze the causes of sudden cardiac death 2 weeks after the onset of acute myocardial infarction (AMI) in the elderly, 12 cases of sudden cardiac death were reviewed, of which 6 were autopsy. It is considered that whether it is the primary ventricular fibrillation caused by unstable myocardial electrical instability or the early complications of infarction, such as body grams, cardiac insufficiency, secondary ventricular fibrillation caused by post-infarction angina are all sudden cardiac arrest The common reason. Autopsy results show that AMI late onset of sudden cardiac death occurred in patients with severe coronary lesions. For patients with high risk of ventricular fibrillation should take active preventive measures, such as the rational use of antiarrhythmic drugs to improve coronary circulation and improve cardiac function, to avoid predisposing factors, can reduce the incidence of sudden death.
