Study summary

Background: The wearable cardioverter defibrillator (WCD) is an established treatment option for patients at high risk for ventricular tachycardia / ventricular fibrillation (VT/VF), either in whom this risk may only be temporarily present, or in patients at high risk for sudden cardiac death (SCD) or after VT/VF in whom an implantable cardioverter defibrillator (ICD is currently not possible for other reasons (infection, recent MI \<40days, recent PCI/CABG \< 3months etc.).

Methods: Comprehensive registry including all patients in Austria who received a WCD in 2010-2016.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 14, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
