Any physical exertion like walking allot or playing five a side football basically anything that gets my heart pumping I start getting heart palpitations they are so annoying and really noticeable to me. They eventually go but can take a while, hot weather doesn’t help either that can cause my heart palps too. I have had about 10 ecgs and bloods over the years and all came back fine. I have never worn a heart monitor or done a stress test. Allot of people say it’s normal especially if i worry allot and get stressed.
