[Continuous observation of catecholamine release into the blood of the coronary sinus in experimental myocardial infarct complicated by ventricular fibrillation].

It was established that the content of adrenalin and noradrenalin in the coronary sinus blood increases after occlusion of the coronary artery. In experiments terminating in ventricular fibrillation the concentration of catecholamines was found to be increased more markedly. A temporary correlation was established between an increase in the catecholamine level in the blood of the coronary sinus and the development of ventricular fibrillation. It is assumed that catecholamines are the triggering mechanism in the development of ventricular fibrillation.
