Energy Drinks Increase Heart Contraction Rate In Healthy People: Study

Caffeinated energy drinks can increase the heart's contraction rates in healthy people, according to a new study. While the potential health risks of this effect are still not known, researchers said the findings suggest people who have cardiac arrhythmia should avoid these drinks because arrhythmia could be triggered by changes to the heart's contraction rates. "We've shown that energy drink consumption has a short-term impact on cardiac contractility," study researcher Jonas Dörner, M.D., of the University of Bonn, said in a statement. ...
