Atrial high-rate episodes (AHREs) characteristics by atrial high-rate episode duration. (A) Number of atrial high-rate episodes prior to at baseline. (B) Time from last adequate atrial high-rate episode to baseline by atrial high-rate episode duration in months. (C) Duration of the maximal atrial high-rate episode at baseline (longest single episode) in minutes and days. The apparent peak at 4 days (99 h) atrial high-rate episode duration is due to the fact that some manufacturers only store precise atrial high-rate episode durations up to 99 h, while other manufacturers and devices precisely capture atrial high-rate episode durations up to 9999 h. All graphs show separate distributions for each randomized group in the 2389 patients with adequate atrial high-rate episode. There were no differences between randomized groups
