为了评价原发性心室颤动前的表现,作者对262例急性心肌梗塞发作6小时内入院而未用抗心律失常药物治疗的患者,连续记录心电图12小时,分析警告性心律失常(每分钟多于5次的室性早搏、早搏指数 QR’/Q-T<0.85、多源性或成对的连续室性早搏)、持续的室性心动过速、原发性心室颤
In order to evaluate the pre-ventricular fibrillation performance, we recorded 262 electrocardiograms (ECGs) continuously for 262 patients admitted to hospital within 6 hours of onset of acute myocardial infarction who were not treated with anti-arrhythmic drugs and analyzed for warning arrhythmias (more than 5 premature ventricular contractions, QRS / QT <0.85, multiple or consecutive pairs of premature ventricular contractions), persistent ventricular tachycardia, and primary ventricular fibrillation
