有些室性心动过速,QRS时限轻度增宽(≤0.12s)常表现为右束支传导阻滞并电轴左偏、右偏或左束支传导阻滞图形。因此类室速异位节律点多位于左束支的某
Some ventricular tachycardia, QRS duration slightly widened (≤ 0.12s) often manifested as right bundle branch block and left axis deviation, right deviation or left bundle branch block pattern. Therefore, ventricular rhythm ventricular rhythm more than in the left bundle branch
