Does beta-adrenoceptor blockade alter cardiopulmonary and hemodynamic adjustments to physical and behavioral stressors?
Tachycardia elicited by behavioral stress is entirely mediated by beta-adrenergic mechanisms and occurs without an appropriate increase in oxygen consumption, suggesting systemic overperfusion.
Langer et al. (1985) studied this question.
