Predictors of response to cardiac resynchronization therapy in patients with chronic right ventricular pacing

ConclusionOnly underlying heart disease (NICM vs. ICM) and the use of ACE inhibitor were significant predictors of response to CRT-upgrade. In contrast to de novo CRT-recipients, where pre-implant QRS-duration is a key predictor, QRS-duration during RV-pacing has no significant impact on CRT-response in this cohort.Graphic abstract
