We evaluated the relationships between the prognosis and the presence of late potentials (LP) on signal averaged electrocardiogram (SAE) in 165 patients surviving an acute myocardial infarction (MI). SAE was performed four weeks after the onset of MI. Arrhythmic events was defined as nonsustained ventricular tachycardia (VT), sustained VT and ventricular fibrillation. LP was detected in 41 (25%) of 165 patients. Patients with LP had dilated left ventricle and lower ejection fraction. At a mean follow-up of 4.4 years, 6 of 124 patients (5%) without LP and 20 of 41 patients (49%) with LP had a late arrhythmic event. Arrhythmic death and sudden death were observed in 2 patients (2%) without LP and in 9 patients (22%) with LP.
我们评估了165例急性心肌梗死（MI）存活患者的预后与信号平均心电图（SAE）上晚期电位（LP）的存在之间的关系。SAE在MI发作四周后进行。心律失常事件定义为非持续性室性心动过速（VT）、持续性VT和心室颤动。165例患者中有41例（25%）检测到LP。有LP的患者左心室扩张且射血分数较低。在平均4.4年的随访中，124例无LP的患者中有6例（5%）发生晚期心律失常事件，41例有LP的患者中有20例（49%）发生晚期心律失常事件。无LP的患者中有2例（2%）发生心律失常死亡和猝死，有LP的患者中有9例（22%）发生心律失常死亡和猝死。
