Which term best identifies the feature on the programmer that is used to initiate atrial fibrillation in testing?

• A. Atrial overdrive pacing
• B. Ventricular pacing
• C. Atr NIPS
• D. Randomized stimulation

Answer: (C)

The concept being tested is how testing environments provoke atrial fibrillation in a controlled way using the device’s programming features. The best term is atrial NIPS, which stands for atrial non-invasive pacing stimulation. This feature allows the tester to deliver targeted atrial pacing sequences without invasive intervention, reliably initiating atrial activity to provoke AF for evaluating detection and response of the device’s therapies. Atrial overdrive pacing is typically used to terminate or suppress tachyarrhythmias rather than to start them. Ventricular pacing targets the ventricle and doesn’t reliably produce atrial fibrillation. Randomized stimulation isn’t a standard, defined testing method. So, atrial NIPS is the correct term for initiating AF in testing.
