I had been to the hospital 2 weeks ago for a sharp burning pain in my heart. I was tod I had a artemia..probaly due to caffine or smoking. My x-rays were ok, and my blood work was fine. I have no clue what they were testing for... so the other day, I started getting a fluter in my chest, which is commen for me...but typically only last a few seconds. This time it turned into a rabit heart beat...so fast I could count and lasted maybe 5 min. I was so scraed...i went to the ER again after it slowed down, where my ECG read... sinus tachycardia, right atrial enlargement, nonspecific t wave abnormality, abnormal ECG.... my heart rate was always between 109-125 at the ER... They say it is most likely PSVT...and my family doc says it could be a birt defect that could be dangurous... I see a cardoligiest on the 26th, but Im afraid. Every doctor I spoke with has warned me if i pass out, its severly bad... whats that mean? any idea what I could have??? I have always been healthy...despite anxiety attacks, now im sooooo scared!!!! Help!
