SVT??

[sasa65]

hi, im a 17 year old male
always been healthy
2 years ago i got a really bad flu and it put me down for a couple of months. from then on i became really weak and i noticed my heart beating. Back then it wast anything sever. A year later i started using Fat burners, that had caffeine and other stimulants in it. All my friends were using it as well. After 3 weeks of using it i got good results. side effects were heart palpitations and high blood pressure due to the caffeine and stimulants. In the summer i got a stomach flu and the symptoms were extreme die rhea and tachycardia. I saw a cardiologist he did ECGS and holtor monitors and said it was normal. But my heart was beating so fast and strong. Anyways he gave me some beta blockers. the summer after that i took fat burners again, this time it was stronger more caffeine. And i only took it for 2 weeks, one day at the gym i did cardio and then when i stepped off the treadmill my heart rate jumped from 120 to 155 and it was beating so fast and heavy so i went to the hospital and they said it was high but still normal rhythm no arrhythmic. Ive seen 5 specialist and they all said the tests were normal echo, ekg, holter monitors. all normal. They said it can** be SVT, but we need to catch the episode and record it while its happening. Now is SVT an everyday thing? or does it come than go? because my symptoms are: hard beat constant 24/7, tachycardia when standing up, or suddenly running or jumping, any sudden movement my heart beats harder and faster. I get tired easily, and this has stopped me from working out. My symptoms get worse after eating!! or before bowl movements , or when i have to use the bathroom. is there any condition that the stomach or intestines get infected and effects the heart? or can it be due to the stimulants in the fat burner? what can i do?

thanks for the reply

I have done 3 holter monitors, all showed no abnormal rhythms or beats, i did a 2 week event monitor, and that was normal aswell. All my ECG's were normal, I have done 2 Echo cardiograms, both were normal and showed nothing. I stopped the fat burners 7 months ago. But my heart rate is still way too hard and can suddenly increase, when i stand up it increase about 10-25 beats, when i say my heart rate is high im talking about up to 130, but this is when im on medication, I take Pro-panololol 40 mg -60 mg everyday. I feel like there is something causing my heart to beat fast, and i think its my intestines, because i feel like there is an infection, i have talked to doctors but they say that your stomach or intestines wouldn't cause a Constant * hard or fast beat. Can this be SVT? i have heard that SVT is only episodes, and nothing constant
