Drinking 32 ounces of an energy drink in a short timespan may increase blood pressure and the risk of electrical disturbances in the heart, which affect heart rhythm, according to a small study published in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

Researchers measured the electrical activity of the volunteers' hearts by electrocardiogram, which records the way a heart is beating. They also recorded participant's blood pressure. All measurements were taken at the study's start and every 30 minutes for 4 hours after drink consumption. Both energy beverages tested contained 304 to 320 milligrams of caffeine per 32 fluid ounces. Caffeine at doses under 400 milligrams is not expected to induce any electrocardiographic changes. Other common ingredients in the energy drinks in the study included taurine (an amino acid), glucuronolactone (found in plants and connective tissues) and B-vitamins.
