Alcohol Consumption and Atrial Fibrillation Study
This study is looking at how drinking alcohol affects people with paroxysmal atrial fibrillation (AFib), which is a type of irregular heartbeat that comes and goes. Researchers want to see if having alcohol leads to more AFib episodes. You would be randomly assigned each day to either avoid alcohol or be allowed to drink alcohol. The study will measure your heart rhythm, alcohol levels, glucose, and fitness over two weeks. To join, you need to be at least 21, comfortable with English, have a smartphone, and have been diagnosed with paroxysmal AFib, with at least one episode in the past month or a healthcare provider's judgment that you could have one. The study aims to enroll 100 participants.
- Study design
- This is a case-crossover randomized study involving 100 participants. Each participant will be randomly assigned daily to either avoid or not avoid alcohol.
- What's involved
- You would receive daily random assignments for alcohol consumption, wear an ECG heart monitor, a fitness tracker, an alcohol monitor, and a glucose monitor for up to two weeks. You would also complete daily morning and evening surveys.
- Compensation
- You may be compensated up to $50 for fully completing the study.
- Follow-up
- The primary outcome, presence or absence of AFib episodes, will be measured at 2 weeks.

What this trial measures
- Presence or Absence of Discrete Atrial Fibrillation Episodes2 weeks
Participants will be wearing a continuously recording ECG monitor for two weeks. The primary outcome will be the presence (versus absence) of at least one AFib episode on randomly assigned drinking versus non-drinking days.
