Official title
Tragus Stimulation to Prevent Atrial Fibrillation After Cardiac Surgery: The TraP-AF Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Patients undergoing cardiac surgery, specifically a coronary artery bypass graft and/or heart valve replacement surgery, are at a higher risk for post-procedure atrial fibrillation (AF). AF is a condition in which the upper chambers of the heart do not contract normally and results in an irregular heartbeat. Recent studies have shown that tragus stimulation decreases the likelihood of AF in animals and humans. It has also been shown to reduce inflammation which may be related to post-procedure AF. Tragus stimulation involves stimulating a part of the outer ear, called the tragus, by sending a microcurrent through a small alligator clip. It is believed that tragus stimulation can affect the nervous system, which may reduce heart rate and lead to prevention of AF. The purpose of this study is to determine whether tragus stimulation in subjects undergoing cardiac surgery will lead to shorter occurrences, or even prevention, of AF.
