The patient is in chronic junctional escape rhythm with no atrial activity noted.Studies have demonstrated normal AV node function.This patient may be a candidate for which type of pacing?
A) Atrial pacing
B) Ventricular pacing
C) Dual-chamber pacing
D) Transcutaneous pacing

Question

Quizplus · Accepted Answer

Pacemakers may be used to stimulate the atrium,ventricle,or both chambers (dual-chamber pacemakers).Atrial pacing is used to mimic normal conduction and to produce atrial contraction,thus providing atrial kick.This is the case in the scenario provided.Ventricular pacing stimulates ventricular depolarization and is commonly used in emergency situations or when pacing is required infrequently.Dual-chamber pacing allows for stimulation of both atria and ventricles as needed to synchronize the chambers and mimic the normal cardiac cycle.However,with this patient,ventricular and AV function are normal.
