Question

Quizplus · Accepted Answer

Beta-adrenergic blocking agents, also known as beta-blockers, work by blocking the effects of adrenaline on the heart, thereby reducing heart rate and strength of cardiac muscle contraction. Digitalis, on the other hand, primarily increases the strength of cardiac muscle contraction, while nitroglycerine and calcium channel blockers primarily work to increase blood flow and reduce chest pain. Anticoagulants work to prevent blood clots, but do not directly affect heart rate or cardiac muscle contraction.
