Po-04-057 atrial fibrillation cured by pacemaker reprogramming

Atrial fibrillation (AF) is commonly detected by remote monitoring of implanted devices. A common question is whether to start anticoagulation in patients with detected AF at risk of stroke. However, the cause of AF is rarely able to be diagnosed or corrected. Repetitive non-reentrant ventriculoatrial synchrony (RNRVAS) is a pacemaker mediated arrhythmia that can occur in patients with intact ventriculoatrial (VA) conduction. Ventricular pacing with retrograde atrial activation that falls within the PVARP is followed by atrial pacing, often delivered while the atrium is refractory.
