Failure of beta-adrenergic blockade to alter ventricular fibrillation threshold in the dog. Evidence for extra-adrenergic effects of pronethalol.
The effects of two beta-adrenergic blocking agents, pronethalol and propranolol, on ventricular fibrillation thresholds were tested in dogs. Pronethalol (4.0 mg/kg, 5 dogs) produced a mean increase of 45% in the fibrillation threshold. Propranolol (0.4 mg/kg, 7 dogs) failed to produce a significant change of the fibrillation threshold. To examine the possibility that the difference between the ...
متن کاملCardiac microcirculatory effects of beta-adrenergic blockade during sympathetic stimulation.
The effects of beta-adrenergic blockade on cardiac transcapillary exchange were examined at rest and during sympathetic stimulation. Multiple indicator dilution experiments were carried out in closed-chest anesthetized dogs at rest and during carotid occlusion, either under basal conditions or after beta-adrenergic blockade with alprenolol. beta-Adrenergic blockade at rest had no effect on coro...
متن کاملBeta-adrenergic blockade reduces myocardial injury during experimental cardiopulmonary resuscitation.
OBJECTIVES We attempted to determine the effects of beta-adrenergic blockade during cardiopulmonary resuscitation (CPR) on defibrillation rates and postresuscitation left ventricular function. BACKGROUND The results of previous studies suggest that propranolol administration can both reduce myocardial oxygen requirements and increase coronary perfusion pressure during CPR. METHODS Left vent...
متن کاملBaroreflex sensitivity in hypertension during beta-adrenergic blockade.
Baroreceptor function was measured in 18 patients with essential hypertension by plotting the change in pulse interval against a phenylephrine-induced transient rise in systolic blood pressure. The influence of propranolol (160 mg daily for at least 4 weeks) on this function and on heart rate after maximal exercise was studied and correlated with the plasma propranolol level. In 13 out of the 1...
متن کاملCardiac Performance with and without Beta Blockade
Systolic time intervals (STI) were measured in ten healthy male volunteers before and after intravenous (i.v.) administration of 25 ,g/kg delta-9-tetrahydrocannabinol (A-9-THC). Mean ± SEM heart rate increased 32 ± 7 beats/min, while systolic and diastolic blood pressures were unchanged after lv-9-THC. Total electromechanical systole lengthened 17 ± 4.2 msec, left ventricular ejection time (LVE...
