为了探讨急性心肌梗死心电图Q-Tc值延长的临床意义,本文分析了42例急性心肌梗死患者的体表12-导联心电图,结果显示:心律失常组Q-Tc间期较对照组显著延长;大面积梗死组的Q-Tc间期及心律失常的发生率均大于小面积梗死组。提示急性心肌梗死的Q-Tc间期与室性心律失常之间有密切的关系。
In order to investigate the clinical significance of Q-Tc prolongation in acute myocardial infarction (ECG), the 12-lead body surface electrocardiogram was analyzed in 42 patients with acute myocardial infarction. The results showed that the Q-Tc interval in arrhythmia group was longer than that in control group. The incidence of Q-Tc interval and arrhythmia in large infarction group were larger than those in small infarction group. Tip acute myocardial infarction Q-Tc interval and ventricular arrhythmias are closely related.
