Question

Quizplus · Accepted Answer

First-degree heart block is a condition in which there is delayed conduction of electrical impulses from the atria to the ventricles. However, all impulses eventually reach the ventricles, resulting in normal ventricular contraction and unchanged cardiac output. Therefore, there is no effect on the cardiac output.
