Question: Hi, I am having a heart-beating-too-fast issue. Lately, in the morning upon awaken, I made it a point to measure my heart rate, and usually it is about 80/min or fewer. Then I do my exercise, which consisting of rubbing my stomach a thousand times, in 100 times per try, after which I measure my heart rate again. It is in the high nineties and usually persists for hours right into the afternoon. I took a cup of very light tea in the interim of my exercise as I afraid that I may have caffeine sensitivity. While I was working several years back, I had a chance to measure my heart rate as well as my blood pressure and heart rate measured were always on the high side(90s-101). I think I was taking at least two cups of strong tea a day. Now that I no longer take strong tea but only exercise, I now still have my heart racing, in the last two or three days, it is confusing to me as the initial reading in the morning is reasonable. Any clue?
