The surdo-cardiac syndrome.
The first diagnosed cases of the surdo-cardiac syndrome are presented. The effect on the ECG of exercise, of digitalis treatment, of intramuscular injection of atropine and of intravenous injection of potassium chloride solution were studied. ECGs taken during attacks of syncope showed that the attacks are caused either by ventricular fibrillation or by ventricular standstill.
