Sponsored by Abbott Medical Devices · Observational
The purpose of this study is to evaluate the application of Negative AV Hysteresis (NAVH) to improve electrical synchrony in MultiPoint Pacing (MPP) Cardiac Resynchronization Therapy (CRT) patients.
5,701 studies on the registry are indexed under Heart Failure; 1,220 are open to participants now.
This study's enrollment of 17 is below the median of 200 across 1,679 observational studies indexed under Heart Failure.
Browse Heart Failure studies →Abbott Medical Devices is the lead sponsor of 525 studies on the registry; 35 are open to participants now.
Of its 52 completed or terminated interventional studies of FDA-regulated products, 43 (83%) have results posted.
