Objective: To assess the cardiac effects of a an energy drink on blood pressure and heart rhythm in healthy subjects. Study design: Double blind, placebo controlled, cross-over Study population: Healthy human volunteers (active-duty) between age 18 to 40 years with no other medical conditions. Intervention: Energy drink or Placebo Primary outcome: Change in office systolic blood pressure
