摘要: 为探讨心肌梗死后存活心肌与心律失常的关系,对98例曾患有心肌梗死的患者,用硝酸甘油介入、99TcMIBI二次扫描方法区分存活心肌,同时用24h动态心电图检测心律失常。结果:有存活心肌组患者较严重心律失常的发生率为58.2%,无存活心肌组为25.6%,2组有显着差异(P<0.01).提示心肌梗死后存活心肌显着增加心律失常的发生率。

Abstract: To investigate the relationship of myocardial viability to the presence of arrhythmia in patients with old myocardial infarction. Ninety-eight patients with previous infarction were studied. Myocardial viabilitis were detected by 99mTc MIBI myocardial tomography with nitroglycerin administration. The presence of arrhythmias was detected by 24 hours ambulatory electrocardiography. Fifty-five patients(56.1%)had improvement of perfusion after nitroglycerin administration, among them, arrhythmias were found in 32 patients(58.2%), comparing 11 patients(25.6%)with arrhythmias in the group without myocardial viability(P<0.01). The presence of viable myocardial in patients with old myocardial infarction have a higher frequency of arrhythmias.

Key words: myocardial viability|arrhythmia|old myocardial infarction
