Case Reports

We present a case of atrial fibrillation with rapid ventricular response in a 28-year-old previously healthy man in the context of daily consumption of 2 Monster energy drinks and 2 to 3 beers. We have obtained consent from this patient to present his case. Our observation adds to the developing literature describing an association between highly caffeinated drinks and adverse cardiovascular events. The previous cases in the literature and the proposed underlying mechanisms of this association are briefly discussed in this article. With the rising popularity of energy drinks, clinicians should be aware of their arrhythmogenic potential and consider screening for these products in patients who present with otherwise unexplained arrhythmias.
