The first large prospective study regarding arrhythmias and alchohol was performed in Munich at Octoberfest in 2015. [24] This study was unique when compared to prior studies in that the study population was an otherwise healthy outpatient population at a festival during acute alcohol consumption. The most common arrhythmia was sinus tachycardia (25.9%); atrial fibrillation (and/or atrial flutter) was seen in 0.8%. When all arrhythmias were considered together, an increasing blood alcohol concentration was associated with an increased incidence of arrhythmia.
