Descriptive Information
Brief Title  ICMJE ASSURE Study - Arrhythmia Single Shock DFT Versus ULV: Risk Reduction Evaluation With ICD Implantations
Official Title  ICMJE Arrhythmia Single Shock DFT Versus ULV: Risk Reduction Evaluation With ICDs Study
Brief Summary The ASSURE Study will evaluate shock conversion performance when programming the first shock of an implantable cardioverter-defibrillation (ICD) is based on an implant test consisting of either 1) a single induction of ventricular fibrillation (VF) and subsequent demonstration conversion success at 14 J or 2) an upper limit of vulnerability (ULV) test at 14 J.
