ASSURE Study - Arrhythmia Single Shock DFT Versus ULV: Risk Reduction Evaluation With ICD Implantations
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
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.
