Brief summary

The DOT-HF trial is an international, prospective, multi-center, randomized, controlled trial.

Detailed description

The study was designed with a Control Arm in order to adequately study the effect of early intervention triggered by the OptiVol® Alert and/or SentryCheck™ Monitor/PatientLook™ Indicator and evaluation using OptiVol® Fluid Status Monitoring with Cardiac Compass. OptiVol® Fluid Status Monitoring with Cardiac Compass features are available in the per Clinical Investigational Plan specified Medtronic products (CRT, CRT-D and ICD devices)
