Assessment of Primary Prevention Patients Receiving an ICD – Systematic Evaluation of ATP (APPRAISE-ATP)- The primary objective is to understand the role of anti-tachycardia pacing (ATP) in primary prevention patients indicated for ICD therapy. The incidence of all-cause shocks in subjects programmed with shocks only will be compared with subjects programmed to standard therapy (ATP and shock) to assess equivalency.
MANAGEment of Atrial Fibrillation Outcomes Registry (MANAGE-AF)-The objective of this multi-site research is to establish a contemporary and simple registry to help determine the course and progression of patients with atrial fibrillation (AF). Its main focus is the management of AF in the prevention of thrombo-embolic events using rhythm and rate control interventions.
PRAETORIAN-DFT- The primary objective is to determine whether the S-ICD implant without defibrillation testing using a new method of measurement (PRAETORIAN Score) is similar to the standard method of defibrillation testing with a totally subcutaneous implantable defibrillation system (S-ICD). The secondary objectives are to evaluate the PRAETORIAN score and to evaluate anesthesia protocols for implantation.
