Question

Quizplus · Accepted Answer

A VVI pacemaker is designed to pace the ventricle and sense activity in the ventricle, inhibiting pacing if the patient's heart rate exceeds a set threshold. It is specifically used to prevent bradycardia (slow heart rate), such as junctional bradycardia, by pacing the heart at a preset rate (in this case, 70 beats per minute) if the patient's intrinsic heart rate falls below this threshold. It does not directly prevent ventricular tachycardia, Torsades de pointes, or supraventricular tachycardia (SVT), as these are issues of too fast a heart rate or abnormal rhythm originating from above the ventricles.
