Digital Exercise Program Using Fitbit to Improve Symptoms in Patients with Paroxysmal Atrial Fibrillation

What This Trial Is About

Atrial fibrillation AF is a common heart condition affecting one in four people during their lifetime, leading to symptoms and health risks. Researchers are evaluating a new approach that uses digital technology to support patient-centered exercise programs aiming to improve AF symptoms and reduce its burden. This interventional study focuses on patients with symptomatic, paroxysmal AF and seeks to establish evidence for a personalized exercise program delivered through wearable technology. The study involves a digital exercise intervention using a Fitbit wearable device to track and encourage physical activity. Participants will undergo a 4-week run-in control period followed by a 24-week physical activity intervention where exercise goals are progressively tailored and monitored via the device. This approach aims to make exercise more accessible and engaging for patients with AF. Participants will be assessed at baseline, after the 4-week control period, and at the end of the 24-week intervention. Evaluations include symptom severity measured by the Atrial Fibrillation Severity Scale AFSS, AF arrhythmia burden through percentage of time in AF and longest episode duration, as well as weekly step counts and exercise minutes. The study also monitors participants adherence to exercise goals and overall health status throughout the trial period.
