Abstract
Estimulante do sistema nervoso central, a cafeína tem sido cada vez mais consumida sob a forma de energéticos. Sendo assim, com o advento de festas regadas a essas bebidas, aumentou-se a procura, por salas de emergência, por jovens e adolescentes, que raramente frequentavam hospitais. Uma vez que possui potenciais efeitos no sistema cardiovascular, desencadeando taquiarritmias e aumento da excitabilidade atrial, inclusive com relatos de casos de hospitalizações e mortes súbitas pela sua toxicidade, a cafeína tem-se tornado alvo de pesquisas médicas. Contudo existe ainda uma carência de estudos e relatos que comprovem essa relação diretamente causal.

ABSTRACT
As a central nervous system stimulant, caffeine has been increasingly consumed in the form of energy drinks. With the advent of parties with lots of these drinks, an increased demand for emergency rooms for youths and adolescents, who rarely attended hospitals, has occured. This has potential effects on the cardiovascular system, triggering tachyarrhythmias and increased atrial excitability, including reports of sudden deaths and hospitalizations due to its toxicity, leading to caffeine becoming a subject of medical research. However there is still a lack of studies and reports that prove this causal relationship directly.
