Exploring the relationship between caffeine consumption and atrial fibrillation

The relationship between atrial fibrillation and caffeine is somewhat complex. The effects of caffeine seem to suggest a proarrhythmic effect, which in reality occurs only in subjects with high sensitivity or following the ingestion of high doses of caffeine. Most population studies do not show a direct link between coffee and arrhythmia; on the contrary, there seem to be beneficial effects on health. It is necessary to explore some issues that remain obscure: the differences between women and men in the response to caffeine and the effects on young people of the high doses of caffeine contained in energy drinks.
