Appearance of a QRS complex after a pacing spike indicates that what has occurred?
A)Atrial capture
B)AV delay
C)Ventricular capture
D)Atrial kick

Question

Quizplus · Accepted Answer

The appearance of a QRS complex after a pacing spike indicates that ventricular capture has occurred. This means that the electrical signal delivered from the pacemaker has successfully depolarized the ventricles and initiated a contraction. Atrial capture (choice A) would be indicated by a P wave after a pacing spike, and AV delay (choice B) refers to the time interval between atrial and ventricular depolarization. Atrial kick (choice D) refers to the contribution of atrial contraction to ventricular filling and is not directly related to pacemaker function.
