Vorhofflimmern - Stabiliserung
Figure 1: Atrial rate stabilization. Premature atrial beat (marked by arrow) occurs 520 ms after stimulated P-wave of DDD Jewel AF ICD pacing. Device starts immediately to stimulate atrium with the same interval (520 ms) plus programmable increment of 120 ms, augmenting the stimulating interval in every second stimulated P-wave (700 + 120 ms, 800 + 120 ms), until an interval of basal atrial stimulation is not obtained (960 ms).

Vorhofflimmern - Antitachykardes Pacing
Figure 3: Termination of atrial tachycardia by antitachycardia pacing. In the upper panel, the atrial tachycardia with a mean cycle length of 440 ms is starting. After detection of tachycardia, the Jewel AF ICD starts with an atrial burst pacing (bottom panel) and terminates tachycardia. AS = atrial sensing, TS = tachycardia sensing, VP = ventricular pacing, TD = tachycardia detection, AP = atrial pacing
