I suffer with health anxiety, social anxiety and GAD. Since i was 17 (currently 30) i have always noticed heart palpations, like little flutters or jumps which can last few secs or a few minutes then they eventually go especially when i am anxious. When i used to play football at 17 i used to get them bad my heart was beating really fast and fluttering/jumping it would scare me but eventually would calm down after a minute or so, i never got chest pain. I have noticed exercise is a big trigger, i could be going for a long walk and i get them, football definitely triggers them and can make them feel worse for some reason, hot weather also and if i am really excited about something that can trigger them too. I have had numerous standard ECG over the years and blood tests and everything came back fine but they are the only tests i have had done. I worry because i know they are other tests that can be done and worry incase they have missed something. Can you get these symptoms even when you aren’t anxious, like a simple walk giving you these heart palpitations for a straight minute or so?!. I also have asthma i know using  your inhaler too much can cause side effects but i don’t. Anyone got any advice, maybe i am just overthinking but seeing young people die in footballer due to heart problems is kinda scary.
