持续性室性心动过速(VT)时,心动周长变异性和这种变异与自行终止VT之间的联系尚未见报道。本文作者对28例冠心病人,55例次持续性VT发作的ECG进行研究,以此掌握持续性VT自行终止前心动周长和QRS波形态变化的特性,确定抗心律失常药治疗对心动周长变异程度。作者观察了VT终止之前第31个～第21个
Continuous ventricular tachycardia (VT), the relationship between cardiac circumference and variability and self-terminating VT has not been reported. In this study, 28 patients with coronary heart disease, 55 cases of persistent VT episodes of ECG study to grasp the continuous VT before its own termination of cardiac cycle and QRS waveform morphological changes in the characteristics of anti-arrhythmic drug treatment to determine the cardiac cycle Long variation degree. The authors looked at the 31st to the 21st before VT was terminated
