Study Summary

This trial is testing whether stimulating the vagus nerve non-invasively can help reduce atrial fibrillation (AF) after cardiac surgery. AF is a common complication after surgery, and can prolong hospital stays. This trial will test whether tVNS can help reduce the burden of AF and days of hospitalization.

Experimental Treatment

Placebo Group

Group I: Intervention GroupExperimental Treatment1 Intervention

Active tVNS (Parasym device, Parasym Health, Inc, London, UK) will be performed with a clip attached to ear at 20 Hz, 250ms at a current just below discomfort threshold for one hour twice a day, starting on post-day 0. Stimulation will continue until 5 days post-operatively or discharge.

Group II: Control GroupPlacebo Group1 Intervention

Sham tVNS will be performed by attaching the Parasym device to the ear and setting output to 0. Stimulation will continue until 5 days post-operatively or discharge.
