title: Effects of cerebral and myocardial ischemia on diving bradycardia in rats.
abstract: The simulated diving in awake rats was performed before, during and after cerebral or myocardial ischemia. Diving bradycardia was attenuated at 1 hr and 3 days, but recovered 7 days after cerebral ischemia. EEG became flat promptly after cerebral ischemia and maintained low amplitude at 1 day, but recovered at 7 days. Diving bradycardia did not change at 1 hr, but was attenuated at 3 and 7 days after myocardial ischemia. A combination of cerebral and myocardial ischemia attenuated diving bradycardia through 1 hr, 3 days and 7 days. The results indicate that either cerebral or myocardial ischemia attenuated diving bradycardia.
