A patient has just returned from the OR after insertion of a VVI pacemaker. In order to assess function of this pacemaker accurately, the nurse needs to understand that:

(A) both atrium and ventricle are paced and sensed and may either inhibit or pace in response to sensing

(B) the ventricle is paced, ventricular activity is sensed and pacing is inhibited in response to ventricular sensing.

(C) both the atrium and ventricle are paced, but only ventricular pacing can be inhibited by a sensed intrinsic ventricular impulse.

(D) the ventricle is paced in response to a sensed intrinsic atrial impulse or inhibited by a sensed intrinsic ventricular impulse.

✔ Correct Answer:

(B) the ventricle is paced, ventricular activity is sensed and pacing is inhibited in response to ventricular sensing.
