Barb, I had palpatations for years. Original docs thought it was a valve issue. It wasn't. I had SVT's - supraventricular tachycardia. My heart would race for no rhyme or reason. You could see my pulse in my neck. For years I could reset it on my own, usually by drinking something very very cold, very very fast. That stopped working. I had to have Adenocard (IV form of defib, aka flatline) several time to reset it. Imagine being awake and getting flatlined - not fun. Finally, a specialist at Baylor diagnosed it as SVTs, went into my heart through a groin artery, did an internal EKG, found the extra "receiver" that I had inside my heart (that's what was creating the "triangular" beat pattern), and zapped it. I was back home that night. No more meds. No more palps. No probs in over 12 years. Wished I'd seen that doc years before. I hope your issue is as simple as mine, and the docs are able to remedy it as easily as mine did.
