Trial Outcomes & Findings for The HOLIDAY (HOw ALcohol InDuces Atrial TachYarrhythmias) Study (NCT NCT01996943)

NCT ID: NCT01996943

Last Updated: 2021-03-16

Results Overview

Induction of Atrial fibrillation will be attempted by pacing and isoproterenol infusion following study drug infusion. The ability to induce atrial fibrillation (yes or no) will be recorded as the primary outcome.

SECONDARY outcome

Timeframe: This will be assessed during the experimental study from the Conduction Times that are measured before and after the study drug infusion. The measurements will be performed within 1 hour of the infusion.

The atrial conduction time will be measured before and after study drug infusion, and the difference between the two times will be recorded as the Change in Conduction Time
