Erratum for Ward et al. Energy Drink–Induced Near-Fatal Ventricular Arrhythmia Prevented by an Intracardiac Defibrillator Decades After Operative “Repair” of Tetralogy of Fallot. Am J Cardiol 2014;114:1124–1125




This paper has errors in Table 1 (either omissions or additions) requiring corrections in the active ingredients of Red Bull, Monster, and Rockstar and in caffeine and sugar content for Rockstar on page 1125.


The corrected Table 1 can be found below.


PoisIndex is a subscription-based database that is used by the US Poison Control Centers and other facilities that tend to toxicity. This, a Mayo clinic publication, and a consumer report study were used preferentially, followed by labelled content on cans. I have clarified where each listed number was obtained. The authors apologize for this error.
