Summary

Patients undergoing cardiac surgery are at high risk of developing atrial fibrillation (AF), with estimated rates of 30-50% and occurs at approximately 2-4 days after surgery. The autonomic nervous system is known to play a key role in AF. Animal studies have indicated that duration and inducibility of AF can be decreased with intermittent vagus nerve stimulation (VNS). In humans, literature suggests that transcutaneous (tragus) VNS (tVNS) can serve as a potentially non-invasive therapy for treatment of post-operative AF (POAF) by reducing inflammation and increasing atrial refractory period. The purpose of this study is to determine the value of tVNS in reducing the burden of POAF and days of hospitalization after cardiac surgery.
