为了阐明急性心肌梗塞后12小时内室性心律失常的自然史,从收住冠心监护病室并确诊为急性心肌梗塞者1,066例中选择有原发性室颤(Pvf)一组17例与无原发性室颤一组21例进行对比。所有病例在症状发作前72小时内未接受过任何抗心律失常药,地高辛或抗利尿药。持续记录的心电图磁带经特殊设计的电子计算系统处理并由3位观察者
In order to elucidate the natural history of ventricular arrhythmias 12 hours after acute myocardial infarction, 17 patients with primary ventricular fibrillation (Pvf) were selected from 1,066 patients admitted to coronary care units and diagnosed with acute myocardial infarction A group of 21 cases of primary ventricular fibrillation were compared. All cases did not receive any antiarrhythmic, digoxin or antidiuretic within 72 hours prior to the onset of symptoms. Continuously recorded ECG tapes are processed by a specially designed electronic computing system and processed by 3 observers
