____, a cardiac glycoside, is a positive inotrope that increases the force and velocity of the contraction of the ventricles while decreasing the velocity of conduction through the AV node.

Question

Quizplus · Accepted Answer

Digoxin is a cardiac glycoside that functions as a positive inotrope, increasing the force and velocity of the contraction of the ventricles. It also has negative chronotropic effects, slowing down the heart rate, and decreases the velocity of conduction through the AV node. Nitroglycerin is a vasodilator that does not affect the force or velocity of heart contractions. Aldosterone is a hormone that regulates electrolyte balance and has no direct effect on heart function. Vasotec is an ACE inhibitor that reduces blood pressure and does not affect the force or velocity of heart contractions.
