AF AND ALCOHOL

A paroxysmal atrial fibrillation (AF) study shows that triggers include caffeine, alcohol, reduced sleep, exercise, lying on the left side and dehydration. But a trials meta-analysis found that alcohol was the only exposure significantly associated with an increased risk of the heart condition. Another study shows that cardioversion of AF back to normal rhythm, whether by direct current or by means of medication, carried a lower risk of mortality if undertaken early.
