Last snipe, promise
Dr. DeGiorgio confirms this observation. Although the heart does function independently, he concedes, "when somebody is truly brain dead, after several days the heart function deteriorates severely. So the heart may function temporarily without a functioning brain, but over a period of a few days, the basic rhythm of the heart will deteriorate, and the patient's blood pressure will deteriorate."
Thus it is possible to test the diagnosis of brain death by continuing to ventilate the patient. If cardio-respiratory death that is, death in the classical sense has occurred, in a short time the patient's heartbeat will slow and become irregular, despite continued ventilation. Eventually, no amount of artificial life support will be able to sustain the heartbeat.
