“…This study revealed an association of energy drink to a QT shortening and increase in a HR percent augmentation, which is consistent with a growing concern of the suspected arrhythmogenic effect of these beverages, which is supported by some case reports of energy drink-related congenital long QT syndrome [57], cardiac arrest [58,59], QTc interval prolongation [60], Brugada syndrome [61] and atrial fibrillation [62,63]. Caffeine is one of the main components that increases QT variability during sleep, which suggests that excessive caffeine intake results in adverse cardiovascular reactions in vulnerable subjects [64].…”

“…We computed that five students who drank EDs every day had a daily intake of caffeine of 400 mg between EDs and other caffeine-containing drinks. This intake is in excess of the maximum daily dose recommended for adults [5,9,10]. …”

“…Rottlaender et al reported a case of a female patient admitted to hospital after consumption of 6 cans of EDs within 4 h [36]. Similar cases have occurred after EDs consumption by a 13-year-old girl [9] and a 23-year-old woman [37]. Persons prone to arrhythmia should be particularly cautious [5].…”

“…A mellkasi elvezetésekben QT-megnyúlás és a magas T-hullámok megszűntek. QT/QTc: 360/430 ms egyéneknél nem találtak jelentős QT-megnyújtó hatást [14,15], míg mások [6,16] -és jelen esetben magunk is -jelentős QT-szakasz-megnyúlást észleltek. Az ellentmondás feloldása valószínűleg a koffein intracelluláris hatásával magyarázható.…”
