Brief Summary:
The purpose of this study is to evaluate the performance of advanced features, that have been implemented in the PARADYM ICD Platform offering single chamber (VR - model 8250), dual Chamber (DR - 8550) and Cardiac Resynchronization System with defibrillation capabilities (PARADYM CRT System, model 8750) in a general ICD population.

Condition or disease Intervention/treatment Phase
Heart Failure Device: ICD Phase 4

Detailed Description:
The study will particularly focus on a new sensor-based diagnostic feature, called PhD-Clinical Status (PhD). A dedicated PhD screen shows the trends of patients' ventilation levels at rest (MVR) and under effort (MVE), and the corresponding level of activity, day-by-day, over a period of 6 months.
