Which feature on the programmer can be used to induce atrial fibrillation in a patient?

• A. Atr NIPS
• B. Vent NIPS
• C. Atrial Pacing
• D. AV nodal stimulation

Answer: (A)

Inducing atrial fibrillation relies on a targeted atrial stimulation protocol that can provoke atrial tachyarrhythmias in someone whose atrial tissue is susceptible. The atrial noninvasive programmed stimulation feature delivers a sequence of paced impulses in the atrium, often with premature or burst stimuli at fast intervals, to test whether AF can be induced. This specific atrial inducibility protocol is what makes AF provocation possible without invasive access. In contrast, stimulating the ventricle would aim to provoke ventricular tachyarrhythmias, simple atrial pacing just maintains rhythm without testing inducibility, and AV nodal stimulation alters AV conduction rather than reliably triggering atrial arrhythmias.
