Optimization of Cardiac Resynchronization Therapy by Non-Invasive Imaging of Cardiac Electrophysiology: A Pilot Study
The principal aim is to analyze total left and right ventricular activation time in different CRT device programming algorithms (SyncAV) measured by non-invasive electrophysiology
Inclusion: patients after successful implantation of a CRT-D or CRT-P device in whom a cardiac magnetic resonance examination is possible and the device is equipped with the SyncAV® programming software; left bundle branch block before CRT implantation; PQ interval ≤ 250 ms before implantation.
Exclusion: drug abusus; terminal heart failure (NYHA IV) or cardiac decompensation; high-grade AV block; any contraindication concerning a safe CMR performance including claustrophobia; life expectancy < 1 year; women with child-bearing potential, pregnancy.
