A. decrease heart rate
B. produce vasoconstriction of the coronary arteries
C. produce vasodilation of blood vessels of skeletal muscle
D. increase heart rate
E. produce bronchodilation

Answer 1

Propranolol, a beta-blocker, is used to decrease heart rate.

Step-by-step explanation:

Propranolol, a beta-blocker, is typically used to decrease heart rate. Beta-blockers block the beta receptors associated with cardioacceleration, which in turn reduces heart rate. By reducing heart rate, propranolol can be used to treat conditions such as hypertension, angina, and arrhythmias.
