When malsensing occurs, a pacemaker may send impulses to the heart during the relaxation phase. What condition may the patient experience if malsensing occurs in a ventricular pacemaker?
A)Ventricular fibrillation
B)SV tachycardia
C)Premature junctional complexes
D)Idioventricular rhythm

Question

When malsensing occurs with a ventricular pacemaker, it can lead to inappropriate timing of pacemaker impulses. If these impulses are delivered during the heart's vulnerable period (T wave), it can potentially trigger ventricular fibrillation, a life-threatening condition characterized by rapid, erratic heartbeats that can lead to sudden cardiac arrest.
