自发现复极延迟与心脏猝死有关以来,Q—Tc 间期一直引人注目。近年来的研究表 明,急性心肌梗塞(AMI)时 Q—Tc 间期的改变为判断其预后的重要参数。本文旨在探讨 AMI 时 Q—Tc 间期延长及延长程度在估价 AMI 近期预后中的价值。资料和方法一.对象1.AMI 组:选 AMI 患者入院时心电图,除外发病一周以上、血清电解质异常和入院前应用影响 Q—Tc 间期的药物者,共60例。其中男42例,女18例,年龄 Since the discovery of repolarization delay associated with sudden cardiac death, the Q-Tc interval has drawn attention. In recent years, studies have shown that the change of Q-Tc interval in acute myocardial infarction (AMI) is an important parameter to judge its prognosis. This article aims to investigate the value of extension and extent of Q-Tc interval in assessing recent AMI prognosis. Materials and Methods I. Subjects 1. AMI group: Electrocardiogram of AMI patients admitted on admission, except for more than one week of onset, serum electrolyte abnormalities and pre-hospital application of drugs affecting Q-Tc interval, a total of 60 cases. There were 42 males and 18 females, of whom age
