Beta-blockers generally have which of the following effects?
A) Increased cardiac conduction
B) Decreased myocardial contractility
C) Vasoconstriction
D) Increased myocardial contractility

Question

Quizplus · Accepted Answer

Beta-blockers are drugs that block the beta receptors in the body, including those in the heart. This leads to a decrease in heart rate, cardiac output, and myocardial contractility. Therefore, choice B is the correct answer. Choice A is incorrect because beta-blockers decrease, not increase, cardiac conduction. Choice C is incorrect because beta-blockers can actually cause vasodilation, not vasoconstriction. Choice D is incorrect because beta-blockers decrease, not increase, myocardial contractility.
