Dr. Milton Alvis, jr answered

Specializes in Preventive Medicine

↑ed rate is only a : sign of ↑ed adrenaline/noradrenaline vs. acetycholine from brain; ↑es heart rate, but not required to achieve benefit of aerobic exercise. Beta blockers = adrenaline/noradrenaline analogues which do not stimulate the beta receptors for these neurohormones yet interfere with their reaching the beta receptors (thus called blockers). Too much adrenaline/noradrenaline damages/kills heart muscle cells.
