About 6/7 years ago I started to have episodes where my heart would go really fast at random for about an hour and then all of a sudden return to normal pace. This happened about 2/3 times a year, but never really caused me a problem. It didnt really interfere with my life and the episodes were so rare somehow they never really worried me. Every time it happened I would get the usual symptoms, such as a very sudden onset of a 200bpm+ heartrate slightly dizzy, sluggish i guess cause of the rush of blood, but every time it happened I knew that I was having the WPW palpitations and they always last up to an hour 2/3 a year.
Last August after I finished my first year at uni I had a night where I went out and I felt what I thought was skipped beats. This worried me a lot and I began to feel nervous and pace up and down but I wasn't alone and I didn't want to act weird. Eventually I started to get the heart skips more and more and as such more and more and eventually I went off by myself to try and find my way home. As I went on I could feel my heartbeat, my stomach felt like it was tightening, I was getting like discomfot in my armpit, pretty intense discomfort like my shirt sleeve was wrapped too tight and eventually my heartrate started to increase. I felt like I couldnt catch my breath at first and it felt worse and worse until I felt like I almost couldnt breathe. It wasnt like a WPW episode because that happenes instantly and there are no prior symptoms, this took a couple of seconds like I broke into a jog but nonetheless my heartrate went up by itself and I thought I was having a heart attack for sure. I phoned an ambulance and when I was waiting I just couldnt sit still I had to move or something and my heart was still going crazy and when the ambulance came and put me on an ecg I saw that my heartrate was 160 bpm even though I was just sitting still. When I got to the hospital I couldnt stop shaking and although my heartrate was high everything else was apparently normal. Basically ever since then I went back to uni and although theres only ever been one time when my heartrate went up and I didnt think it was WPW, I get the other symptoms all the time, especially feeling like i cant quite catch my breath, shortness of breath, rush of blood to the head? dizzyness armpit tightness and especially bloating/stomach tignthness. This has been going on for 9 months and happenes everywhere at lectures on coaches when im going somwhere etc.. so it is stopping me from living my life and a lot of the times forces me to be at home although it can happen just at random and often does. Can someone suggest what this could be or maybe explain whats happening to me? Is it all down to WPW or could I have another problem, maybe a stomach problem due to the stomach tightening, I have had a stomach infection when I was little and I recently started having stomach pains sometimes. I am currently set to have an ablation soon and im on beta blockers right now. I still have WPW episodes and they have no prior symptoms and always last an hour or less. I went for ecg's holter monitors and scans and they all showed up normal. I also recently have been having very slight heart pains maybe twice for like 10 seconds every time i feel my heart beat, but this has only happened like twice. Sorry for the long read.
