rapid heart rate, small amount of caffiene

[Arbutus]

I recently had a heart rate of 120 for five hours after having a pop with 23 to 46 mils of caffiene in it with dinner. Is this normal for that amount? How long does caffiene usually affect you for?  I went to the hospital and they said I had a slight fever (I told them I'd had root beer, but neither the MD nor I thought it had caffiene in it). My EKG was fine and my thyroid was hypo, not hyper  I am a chunky woman in my early 40s.

About a year ago I had a reaction to a medication. for 30 + minutes I had a pounding heart, very heavy sweats and a lot of little round black spots in my vision. These symptoms subsided, but I did go to a hospital with an urgent care centre about an hour later and they told me it was a panic attack and gave me an adavan. About two hours later they told me I'd had a heart attack, gave me an asprin, and transfered me to a larger hospital where they put me on a beta blocker and heprin for a few days, gave me a MIBI, and sent me home because there was nothing wrong. They said that the medication had made my heart race and stressed it (and my kidneys) so my trop (?) had gone up, making it look like I'd had a heart attack. They told me to go to a hospital if my heart rate stayed at 120 for more than 20 minutes so they could see what was going on. My trop came down while I was in hospital and my kidneys tests were fine soon after. I stopped taking the medicationsoon after, but ever since my pulse has been 80 to 100. In the first few months after I had some dizzy spells followed by no more than 10 minutes of a 120 pulse.

Caffeine affects people differently but I would be surprised than one soda would give much of a reaction, unless there was an allergic reaction, not necessarily to the caffeine.

Given you have had some heart checks by a medical doctor(s) and all looks good, I'd suspect emotions/anxiety/ or other reaction to stimulus - can you associate any stimuli with the heart events?

Of course, a "healthy heart" life style would help some, and that will build over the years.  Try to get weight in line with recommendations and exercise (helps with the weight too) enough to build some cardio stamina.  I firmly believe this along with a positive and optimistic attitude will help you.

I think you mentioned you drank a root beer? I dont think root beer has caffeine in it, I know i drink root beer occasionally because I can't have caffeine ( I have afib).
