For the study published in the Journal of the American Heart Association, lead author Sachin A. shah professor of pharmacy at the University of Pacific enrolled 34 adults aged between 18 and 40.
After an overnight fast volunteers consumed two 16 ounces bottles of one or two energy drinks containing carbonated water, lime juice or cherry flavor. The study was double blinded neither the researchers nor the participants know who drank which product.
The researchers then measured the heart rhythm and blood pressure after 30 minutes for a total of 4 hours.
After that the researchers found a significant increase in the time that heart chambers started to contract and relax. This measure is known as QT interval. Heart rate is linked to length of QT interval. Scientists often use corrected QT interval QTc for heart rate.
QTc ranges from 431-450 ms in men or QTc ranges from 451-470 ms is considered maximum heart rhythm.
When this numbers increase its normal person’s risks of cardiac arrest, or disturbances in normal heart beat.
Researchers saw signification changes in length of QT interval in span of 4 hours after the participants consumed energy drinks.
