两组动态心电图(DCG)结果表明,扩张型心肌病(DCM)其心律失常较陈旧性心肌梗塞(OMI)明显。DCM严重室性心律失常多见,其发生与病情、病程及心脏大小无关;与活动和精神因素有关;通常短阵室速不转化为心室纤颤,心房纤颤DCM亦多见。OMI急性期发生心室颤动复苏存活及形成心室壁瘤者未检出室性心动过速。 Two sets of ambulatory electrocardiogram (DCG) results show that dilated cardiomyopathy (DCM) arrhythmia than the old myocardial infarction (OMI) significantly. DCM severe ventricular arrhythmia more common, its occurrence and disease, duration and heart size has nothing to do; and activity and mental factors; usually short-staged ventricular tachycardia is not converted to ventricular fibrillation, atrial fibrillation DCM is also more common. Ventricular fibrillation in OMI acute stage of survival and recovery of ventricular fibrillation were not detected ventricular tachycardia.
