Intracoronary chemical injection to ablate ventricular tachycardia is a new method. Through experiments in 22 dogs, we studied the pathologic change of the myocardium and its mechanism following intracoronary injection of 96% ethyl alcohol. All dogs receiving ethyl alcohol injection displayed myocardial necrosis, and most of them presented thrombus in the coronary branch. The pathologic change in the acute period may have resulted from direct ethyl alcohol damage, and that in the late period may have resulted from both direct damage and thrombus caused by arterial damage.
冠状动脉内化学注射消融室性心动过速是一种新方法。通过对22只犬进行实验，我们研究了冠状动脉内注射96%乙醇后心肌的病理变化及其机制。所有接受乙醇注射的犬均出现心肌坏死，且大多数犬的冠状动脉分支出现血栓。急性期的病理变化可能是由乙醇直接损伤所致，而后期的病理变化可能是由直接损伤和动脉损伤导致的血栓共同引起的。
