Named dangerous drink for the heart Scientists from the Pacific University in the United States found that energy drinks can provoke an increase in blood pressure and heart rhythm disturbances.

Experts conducted a study involving 34 healthy volunteers aged 18 to 40 years. For an hour, they needed to drink about a liter of energy drink or its substitute with a placebo effect.. Energy drinks contained 304-320 mg of caffeine per liter. It was necessary to drink drinks no faster than 0.5 liters per half hour.

Before the experiment and every 30 minutes for 4 hours after drinking, volunteers measured blood pressure and recorded cardiac activity..

It turned out that those who drank energy drinks QT interval - an indicator of heart activity - was 6-7.7 milliseconds longer for 4 hours. Experts have noted that too long or too short a QT interval can lead to abnormal heartbeats and life-threatening arrhythmias.. In addition, the subjects had a significant increase in systolic and diastolic blood pressure..
