Caffeine-based Beverages Linked to Abnormal Heart Rhythm – the Truth








All the caffeine-based beverages we consume frequently might trigger abnormalities connected to our heart rhythm and other cardiovascular diseases. These types of drinks can make our blood pressure higher and can sometimes make us feel more anxious than usual.

However, scientists are still not hundred percent sure whether they have this effect on us because they contain caffeine. Doctor Michael White that also teaches at the University of Connecticut has stated that drinking energy drinks is not necessarily unhealthy or dangerous for our health. Although the drink by itself will not cause danger, people that have a bigger possibility to develop heart problems and also drink this type of caffeine-based beverages might notice some negative effects from these drinks. Easily put, it means that some individuals should not be drinking energy drinks in order to prevent more serious cardiovascular diseases.

Comparing coffee and energy drinks, you can easily see the massive difference between these two. For example, about sixteen-ounce cans of the Rockstar energy drink contain around 160 mg of caffeine and 6-ounce cup of freshly made Nescafe or some other strong brand of coffee contain about 100 mg of caffeine. However, we should not ignore the fact that apart from caffeine, these beverages contain a lot of sugar and some herbs that can have a negative effect on your body if you consume them altogether.

The managers of the brands and other individuals that represent the industry of energy drinks are saying that they are not dangerous and that the amount of caffeine they contain is not really menacing for people’s health. Scientists have been looking at the results of several studies that were based on caffeine-based beverages and have found out that about 93 applicants that were drinking these beverages went through an EKG test, and even a larger number of the applicants went for a blood pressure check.

All of the applicants were generally drinking at least one can of Red Bull. The researchers have gone through the results and noticed that the QT intervals were longer due to the fact the applicants were drinking these types of drinks. Doctor Riddock had stated that the team that is working on the research believes that this state has been caused because of the sugar and herbs that the caffeine-based beverages contain, not because of the caffeine.

The EKG test is an electrocardiogram measurement that helps doctors find out whether the heart is beating properly and how long the intervals (QT intervals) last. If the QT intervals are longer, the person is in danger and he might die because of low functioning of the cardiovascular system.

Apart from finding out about that particular effect, the doctors have found another undesirable effect that was triggered by the consumption of energy drinks. They had found out that the applicants that went through a blood pressure measurement had gone through a major change – their blood pressure jumped by 3.5 points but only shortly after they drank the caffeine-based beverage!
