心肌梗塞后发生突然死亡,常因心律失常所致,此种情况与交感神经活动有关。动物实验与临床经验显示,预先应用心得安、心得宁或心得舒,可防止心室颤动阈的降低。β-肾上腺素能受体阻滞剂能明显降低实验性冠状动脉阻塞后的死亡率。但心肌梗塞后病人的应用结果,尚有分歧。本文报告3038例病人在梗塞后7～28天起,应用双盲法作
Sudden death after myocardial infarction, often due to arrhythmia, this situation is related to sympathetic activity. Animal experiments and clinical experience show that the application of propranolol, experience rather or feel comfortable, to prevent the reduction of ventricular fibrillation threshold. Beta-adrenergic blockers significantly reduced mortality after experimental coronary occlusion. However, after the application of myocardial infarction patients, there are still differences. This article reports 3038 patients 7 to 28 days after infarction, the application of double-blind method
