In a study that tracked roughly 386,000 people for 4½ years, drinking coffee wasn’t linked to a higher risk of irregular heart rhythms like atrial fibrillation or ventricular tachycardia.

Though the study couldn’t prove that coffee is safe for the heart, the authors accounted for factors like smoking, exercise, and genes that affect caffeine intake.

What to do

Relax. It’s unlikely that coffee causes irregular heart rhythms.
