Exercise After an Implantable Cardioverter Defibrillator (ICD)

This study is looking at how effective a home-based walking program, called E-ICD, is for people who have received an implantable cardioverter defibrillator (ICD). An ICD is a small device placed in your chest or abdomen that helps regulate your heart rhythm and prevent sudden cardiac arrest. The E-ICD program involves walking at home three days a week for 12 weeks. Researchers want to see if this program helps you be more active in your daily life. You may be able to join if you are over 18, have an ICD, can walk for at least 5-10 minutes a day without help, and can read, speak, and write English. The study plans to enroll 210 participants, but its current status is unclear.

Study design
This is a randomized study comparing the E-ICD intervention to usual care, with 210 participants planned across three sites.
What's involved
You would participate in a 12-week home walking exercise program. Your daily activity will be measured at the start, 3 months, 6 months, and 12 months.
Compensation
Not stated in the trial record.
Follow-up
Your daily activity will be measured at 3, 6, and 12 months after the start of the study.
