Cardiac Rehab Retrospective Review (CR3)

Medical University of Graz55 enrolled

Overview

All patients enrolled in the Austrian LifeVest Registry will be retrospectively screened for successfully completed ambulatory or stationary rehabilitation program. Baseline characteristics, complete rehab data, outcomes and follow up data, as well as wearable cardioverter defibrillator(WCD)-derived data will be collected from these patients. Specifically, performance data from the start of the exercise training (ET) will be compared to the end of ET; including type of training, exertion, time and duration will be collected. In addition, WCD recorded data such as automatically and manually recorded ECGs, compliance, and TRENDS data will be collected.
