Energy drinks have received much publicity worldwide due to concerns of adverse effects
on health to consumers [
[1]
] The reporting of adverse effects (including cardiac symptoms) related to consumption
has increased [
[3]
] along with their popularity [
].Concerns that these drinks may unmask a life threatening ventricular arrhythmia have
been raised [
[4]
] due to reports of ventricular arrhythmias [
[5]
] and death [
[6]
] while consuming energy drinks. Given the potential adverse effects of energy drink
consumption we conducted a survey to determine the impact of these drinks on emergency
department presentations in otherwise healthy young adults. See Table 1, Table 2.
