Full-Avoidance vs. Permissive/Regulated Drinking & Outcomes On Fibrillation

The goal of this study is to assess the short-term effects of minimal and moderate drinking on atrial fibrillation (AFib) episodes in a real-world population diagnosed with 'come-and-go'/paroxysmal AFib. The question it aims to answer is:

Is there a greater occurrence of AFib episodes when participants are allowed to consume alcohol according to random assignment?

Participants will:

• Be given daily random assignments to avoid or not to avoid alcohol
• Wear an adhesive electrocardiographic (ECG) heart monitor
• Wear a wrist-worn fitness tracker
• Wear an anklet transdermal alcohol monitor
• Wear an adhesive glucose monitor
• Complete morning and evening surveys daily

Participants may be compensated up to $50 for full completion of the study. This study can be done in-person or remote.

This study is a case-crossover randomized trial, where each participant will be instructed to avoid or not avoid drinking alcohol on randomly assigned days during a 14-day monitoring period. Participants will also wear an external ECG monitor, an alcohol monitor, a continuous glucose monitor, and a fitness tracker for up to two weeks while utilizing a mobile application to receive daily instructions/reminders on drinking and short surveys. The investigators will compare participant self-report of alcohol consumption, glucose monitoring, fitness levels, sleep health, and heart rhythm data in order to better understand the immediate relationship between drinking alcohol and heart rhythm. A total of 100 participants will be enrolled.
