When is a ventricular pacemaker used alone?
A)When both the atria and the ventricles need to be stimulated to contract
B)When the atria need to contract completely before the ventricles to allow for an atrial kick
C)When the conduction system from the AV node through the ventricles is intact and functioning
D)When conduction in the ventricles is not working properly, so the ventricles must be stimulated to contract

Question

Quizplus · Accepted Answer

A ventricular pacemaker is used alone when the conduction system in the ventricles is not functioning properly, and therefore the ventricles need to be stimulated to contract. This is often seen in cases of complete heart block or other types of ventricular conduction abnormalities.
