Upper-extremity exercise options for people with heart failure and implanted devices
This study tests different upper-extremity exercise programs to see which helps people with heart failure and implanted defibrillators or CRT devices improve arm function.
-
Optimal ATP settings for new ICDs in heart disease patients
This trial tests whether Burst or Ramp ATP settings in the VT zone of a new ICD help patients with heart disease.
-
Belgian registry for extravascular ICDs to track real-world use
This Belgian registry follows adults with extravascular ICDs to see how the devices perform and what issues arise over time in routine care.
-
Carvedilol versus metoprolol succinate in people with heart failure and an implanted defibrillator
This study will test whether switching from metoprolol succinate to carvedilol reduces ICD therapies, heart-related hospitalizations, or cardiovascular death in adults with HFrEF and an ICD.
-
CHOICE-ICD: online education and support for people with an implantable cardioverter defibrillator
This project will test an online education and support program (CHOICE-ICD) for people awaiting or recently fitted with an ICD and their families to help lower anxiety and improve quality of life.
