Energy Drinks Induced Atrial Fibrillation

Abstract

Introduction: Atrial fibrillation (AF) is most common in adulthood supraventricular arrhythmia. Some of our ways of life the occurrence of this arrhythmia possible. Recently, it is common to consume energy drinks (ED), especially among young people. Caffeine is found in energy drinks. Their adverse effects, not yet completely known, are usually considered secondary to a high concentration of caffeine. Here we focus on a particular acute cardiac complication of EDs overconsumption: atrial fibrillation.
 
 Case report: A 23-year-old man, was referred to our emergency department for dyspnea, palpitations, and anxiety. The patient had a negative family, personal, and pharmacological history. About two hours before, he has consumed 750ml of ED. At admission, blood pressure was 104/62. An ECG revealed a high rate of atrial fibrillation at 162bpm. Laboratory investigation revealed that complete blood count and routine biochemical blood levels were within normal limits. Transthoracic echocardiogram excluded the presence of cardiac disease, the left atrium was slightly dilated, as expected. According to guidelines patient was treated with propafenone and recovered a normal sinus rhythm.
 
 Conclusion: As in our case, PAF can occur due to ED consumption, and awareness about this adverse effect of ED consumption is important.
