A study was conducted on the effects of cardiac arrest on cardiac functions by means of anoxic arrest and electric fibrillation under conditions using pump-oxygenator and extracorporeal circulation in dogs. The results were examine on the basis of the Saroff's cardiac function curves. Thirty-minute application of the pump-oxygenator had no effect on cardiac functions. Neither electric fibrillation nor anoxic arrest caused a significant change in cardiac functions. Synchronous performance of electric fibrillation and aorta blocking had significant effects on cardiac functions. For a short-duration cardiac arrest in open heart surgery, it may be advisible to use either electric fibrillation, anoxic arrest, or a combined method of electric fibrillation and aorta blocking depending on the cases.
