Digoxin exerts a (-) chronotropic effect and (+) inotropic effect.Which of the following describes these effects?
A)Slows heart rate and decreases cardiac output
B)Increases heart rate and increases systemic vascular resistance
C)Decreases heart rate and decreases stroke volume
D)Decreases heart rate and strengthens myocardial contraction

Question

Quizplus · Accepted Answer

Digoxin is a medication commonly used in the treatment of heart failure and atrial fibrillation. It exerts a negative chronotropic effect by slowing heart rate, and a positive inotropic effect by strengthening myocardial contraction. This results in an increase in stroke volume, and subsequently, an increase in cardiac output.
