Improvement of electrical synchrony in CRT using dynamic atrioventricular delay programming and multipoint pacing

Conclusion: SyncAV and MPP improved acute electrical synchrony in CRT. Combining both technologies with patient-specific optimization resulted in greatest improvement, regardless of time since implantation.Whats newNovel device-based algorithms like a dynamic atrioventricular delay algorithm (SyncAVTM, Abbott) and multipoint pacing (MPPTM, Abbott) aim to simplify CRT optimization. Our data show that a combination of patient tailored SyncAV optimization and MPP results in greatest improvement of electrical synchrony in CRT measured by QRS duration, regardless if programmed in newly or chronically implanted devices. This is the first study to our knowledge to examine a combination of these device-based algorithms. The results help understanding the ideal ventricular excitation in heart failure.This article is protected by copyright. All rights reserved
