Summary The initial hypotension and bradycardia after ECT are greater with auricular stimulation than with forehead stimulation. The subsequent hypertension and tachycardia are also greater with the former. If the shock is repeated, the initial bradycardia and the subsequent hypertension are maximum with the first convulsion, and least in the third. Blood pressure, central venous pressure and cerebrospinal fluid pressure also rise and reach a maximum 30 sec. after the shock. Five to ten min. after the convulsion they slowly return to initial level, although blood pressure and central venous pressure remain above normal until 10 min. after ECT. Decrease in arterial pH and Po 2 , and increase in arterial Pco 2 and potassium occur without premedication and anesthesia, but not with premedication and anesthesia.
