  Purpose

The COGENT-4 Field Following Study will evaluate the clinical performance of the Boston Scientific TELIGEN 100 HE Implantable Cardioverter Defibrillator (ICD), the COGNIS 100 HE Cardiac Resynchronization Therapy ICD (CRT-D) systems and the RELIANCE 4-SITE defibrillation lead (when available). An optional sub-study will also evaluate the clinical performance of the Reverse Mode Switch (RMS) feature in the TELIGEN 100 HE DR ICD.
