Hello, this may be long and i am sorry for that.But i really need help as i will not have insusance for another 2 months..... I am a 23 year old male that was diagnosed with svt at 21. was misdiagnosed for years. They thought it was panic attacks and i could never get it on a ekg for them. but i would natualy use the vegal( spelling ) manuever and get it back to beating right. like it would go beat,beat,beat,beat,,beat.......BEAT. I would fell it in my throat and get a little dizzy. The last one would beat hard then back to normal. One day i got it on there. 7 years later. I ended up getting an EP study with ablation and the dr said thet he believes that it is gone.they did the sonogram ( spelling?) and said all my chambers look right and healthy. My heart does not look enlarged etc.looks good. but Small chance it would come back. ( the SVT)I have not gone back into SVT ( truly a blessing) Now for the last couple years it has started doing something new. It slows way down. like to 40 bpm. skipped beat all in there.Now when it starts beating all over the place it will get as high as 84. Lately it has been doing that ALL day.Beat kinda regular then slow WAY down. Like hard thuds. beat normal ( but still skipping) I feel it in my throat as i did when i had SVT. it affects my breathing really bad ( not hard to breath) just affects it. A little dizzy sometimes and downright fatigued when it is beating slow.( as i was when it was fast) I feel better when it gets a rythem to it. Like i will be fine then it just starts doing it and i usually just stay still till they pass. Now i know i need proper evaluation in a cardioligists office. But i would be very grateful if you could answer these questions...1) What to you believe to be the problem. Or maybe a small list of what it can be.2) when it beats like that is it ok to exert myself (run with it is beating like that)? 3) Could it possibly be PCS's all day? can that happen? What can i do to prevent it or make the "spells" not as long? 4) does it sound deadly?..........Other info. i have never passed out. even with the svt. i smoke. trying to quit. i am really stressed. and believe me this does not help.Drink caffine. Again i am very sorry for the length but. I could really use some help.. any info would be greatly appreciated. Thank you- Austin
