What effect does caffeine has on your Heart?
Ever since I started meeting new clients with a heart rhythm disorder (“heart skips a beats” / “heart started racing”), I have personally decided to stop consuming any form of caffeine mainly due to the wide-ranging research that suggest that caffeine could aggravate the heart. Despite this, today society usage of caffeine is at an all-time high as it comes in numerous forms such as coffee, energy drinks/ sachets, sports performance drinks etc…
It turns out caffeine does in fact affect the heart (within the 30 – 60 minutes absorption period). High doses of caffeine increase the level of epinephrine (adrenalin) within the blood vessels. As a result, epinephrine is extensively connected with raising blood pressure, increasing the force or contractility of the heart, and slightly raises the heart rate.
Back to the reason why I have personally decided to stop consuming any form of caffeine;
It is widely known that diagnosed heart rhythm disorder patients are prone to abnormal heart rhythms. Consequently, high doses of caffeine can cause the heart to develop skipped beats ranging from the lower or upper heart chambers or encounter palpitations resulting from a rapid heart rhythm.
Most heart rhythm disorder patients that I came across, stated that when they consumed high doses of caffeine, there were an “uncomfortable sensation of the heart beating”. This is due to the typically association of increased levels of epinephrine in the blood stream that contributes to increased rate force of each heartbeat and heart rate. On the other hand, if the caffeine contributes to the abnormally heartbeat, the abnormal heart rhythm can continue when caffeine levels are very low or absent. Consequently, the consideration of a trial that entails of cessation caffeinated products is always a bright idea if you have experience an abnormal heart rhythm or any new heart symptoms (uncomfortable sensation of the heart beating rapidly or heart skips a beat).Then again, most people who often relish caffeinated products bodies has a tendency to develop an tolerance to caffeine and the effects on the heart are diminished. Yet for the utmost of patients that have consumed caffeine for countless years, caffeine is indecently associated with the development of new abnormal heart rhythms.
To put it briefly, when you start consuming caffeine or high doses and begin to feel abnormal heart beats or rhythms, it is advised to stop consuming caffeine. As a result, it may take a few days for the heart to return to normal after the exposure to caffeine. However, if the symptoms (uncomfortable sensation of the heart beating rapidly or heart skips a beat) are severe, consult your general practitioner. On the other hand, if you experience these symptoms after numerous of years consuming similar levels of caffeine, then your heart related symptoms are probable triggered from other sources.
