While the study points out that about one to four percent of the general population has cardiac arrhythmias, i.e. irregular heartbeats, 30.5 percent of study participants had irregular heartbeats and nearly 30 percent of them were sinus tachycardia, a condition where the heart beats too fast. Scientists found a direct link with alcohol: People who had higher blood alcohol levels were at a significantly increased risk of having a heart arrhythmia. (Looking to improve your diet?

Why should you care? Researchers point out that in some situations, arrhythmias can cause atrial fibrillation, an irregular heartbeat that can be severely uncomfortable. And, in the long run, they can cause more serious problems like heart failure and stroke.
Drinking a lot over a short period of time (like many people do at festivals) has been linked to a condition called “holiday heart syndrome” where people who have no history of heart issues develop arrhythmias and sometimes atrial fibrillation.
Scientists suspect that the arrhythmias they found during the festival were temporary and would go away once the study participants sobered up, but they’re not totally sure since they only took measurements when they had been drinking.
Bottom line: Take it easy on the booze—especially if you have a heart condition. You could be left with more than a nasty hangover if you don’t.
