  Purpose

Primary Objective:

To characterize left ventricular (LV) threshold behavior over time using daily left ventricular capture management (LVCM) measurements.

Study Design:

This is a multicenter, prospective, non-interventional study with patients receiving their first cardiac resynchronisation therapy-implantable cardioverter defibrillator (CRT-ICD) device. The study design, based on the primary objective, is an observational examination of LV thresholds over time. Daily left ventricular threshold measurements will be collected using the LVCM feature. Up to 150 patients will be enrolled in Canada to evaluate the primary objective at up to 15 study centers.

Data will be collected at Baseline, Implant, 12 months post-implant and all regularly scheduled follow-up visits up to 12 months post-implant.

Devices:

The ConcertoTM CRT-ICD device and future Medtronic CRT-ICD devices containing the LVCM feature will be used in this study.
