自1978年至1991年4月,我科对2455例冠心病、可疑冠心病和常规心电图(ECG)发现心律失常患者进行了动态心电图监测。检查前三天停用所有抗心律失常药物。采用美国Delmar Avionics携带式磁带连续记录仪,660A系统计算机扫描分析和Amb-Watoty DCG系统4310S半导体记录仪分析进行监测。室性心动过速(VT)的诊断标准为:连续三个以上、快速、宽大畸形的QRS-T波群,其前无相关的心房波,QRS间期≥0.12秒,QRS-T波形与同导联室性早搏波形相同。心室率≥60次/分,其中除外室性心动过速伴室内差异传导,束支阻滞及预激
From 1978 to April 1991, our department performed dynamic electrocardiogram monitoring on 2455 patients with coronary heart disease, suspected coronary heart disease and conventional electrocardiogram (ECG) arrhythmia. Disable all antiarrhythmic drugs on the first three days of the exam. Monitoring was performed using the Delmar Avionics Portable Tape Continuous Recorder in the United States, a 660A system computer scan analysis, and the Amb-Watoty DCG System 4310S Semiconductor Recorder. Ventricular tachycardia (VT) diagnostic criteria: more than three consecutive, rapid, large deformity of QRS-T wave group, before the relevant atrial wave, QRS interval ≥ 0.12 seconds, QRS-T waveform and the same Lead ventricular premature beats the same waveform. Ventricular rate ≥ 60 beats / min, except for ventricular tachycardia with differential conduction indoors, bundle branch block and pre-excitation
