  Purpose

In patients with a standard indication for pacing and no previous history of AF, detection of Atrial High Rate Episodes predicts an increased risk of stroke and systemic embolism.

Overdrive atrial pacing with the AF Suppression algorithm will reduce the risk of symptomatic AF in patients with standard indication for pacing and no previous history of AF.
