Two different monomorphic VTs were observed in two patients after a corrective operation for tetralogy of Fallot. The activation pattern of the wavefronts of the two VTs were different: in a counter-clockwise direction around the anatomical obstacle due to a ventriculotomy of the right ventricle in one VT; and in a clockwise direction around the same obstacle in the other VT. The different revolutions of the wavefronts could be the mechanism for the different morphologies of VT.
在两名法洛四联症矫正手术后的患者中观察到两种不同的单形性室性心动过速。两种室性心动过速的波前激活模式不同：一种室性心动过速中，由于右心室心室切开术，波前围绕解剖学障碍物呈逆时针方向；另一种室性心动过速中，波前围绕同一障碍物呈顺时针方向。波前的不同旋转方向可能是室性心动过速形态不同的机制。
