急性心肌梗塞(AMI)晚期最常见的死亡原因为室性心律失常。患者即使在心律失常开始发作时得以复苏,但梗塞后晚期预后仍较差。本文报道53例患者临床和电生理特征以及内外科治疗的结果。方法:53例病人均系 AMI 后2天～2月期间出现一次以上持续性室性心动过速(Sus VT)或心室纤颤(VF)的存活者,男性43例,女性10例,年龄61±10岁。凡主要因梗塞范围扩大或进行性循环衰竭引起的心律失常均未列入。电生理检查在停用抗心律失常治疗24～48小时后进行。对程序心室刺激未能诱发出临床发作的心律失常者隔日重复刺
The most common cause of death in late AMI is ventricular arrhythmia. Patients recover even when their arrhythmias begin to attack, but the prognosis for the late post-infarction is still poor. This article reports the clinical and electrophysiological characteristics of 53 patients and the results of surgical treatment. Methods: Fifty-three patients were survived more than one time of persistent VT or VF after 2 to 2 months of AMI, including 43 males and 10 females, aged 61 ± 10 years old. Arrhythmias due to an increase in infarct size or progressive circulatory failure were not included. Electrophysiological examination in the withdrawal of anti-arrhythmia treatment after 24 to 48 hours. Procedural ventricular stimulation failed to induce clinical episodes of arrhythmias repeated spines every other day
