Alcohol appears to have an immediate—or near-immediate—effect on heart rhythm, significantly increasing the chance that an episode of atrial fibrillation (AFib) will occur, according to new data presented at the American College of Cardiology’s 70th Annual Scientific Session.
The data revealed that just one glass of wine, beer or other alcoholic beverage was associated with twofold greater odds of an episode of AFib occurring within the next four hours. Among people having two or more drinks in one sitting, there was a more than threefold higher chance of experiencing AFib. Using an alcohol sensor placed on participants’ ankles, which passively monitored alcohol intake, the investigators found that every 0.1% increase in inferred blood alcohol concentration over the previous 12 hours was associated with an approximate 40% higher odds of an AFib episode. Evidence from those sensors also demonstrated that the total alcohol concentration over time also predicted the chance AFib would occur.
