title: [Study of the effect of ethaverine and papaverine on post-ischemic arrhythmias in the awake dog].
abstract: Influence of ethaverine was compared to papaverine on the development of dysrhythmias observed in the unanesthetized dog following coronary ligation. Papaverine generally induced the reappearance of ectopic beats. In most cases, ethaverine induced the normalization of the electrocardiogram. This favourable effect of ethaverine distinguished it from papaverine; however it was moderate, transient and weaker than that of classical antidysrhythmic drugs. According to these results and those of previous experimental data, ethaverine seems to be devoid of "malignant properties".
