| Popis: | The immediate effects of ECS on the carotid blood flow, arterial pressure, and cardiac rate were recorded in experiments on a series of 16 unanesthetized dogs. The shock stimulus in terms of milliamperage, voltage, and duration of the electrical current were also recorded. Blood flow was measured continuously by the use of an electromagnetic blood flow meter. Blood pressure was measured directly and continuously in the femoral artery through the use of a Statham Gage-Brush recorder system. All operative procedure was carried out under general ether and/or local procaine anesthesia. The initial responses to ECS were convulsions, respiratory arrest, bradycardia, and reduced carotid blood flow and arterial pressure; the latter 3 responses had a duration of one second. The bradycardia could be prevented by vagotomy. The initial decrement in these entities was followed by a prolonged secondary increase above control levels. Blood flow and arterial pressure reached their highest elevations concomitantly and the... |
