Well, I found out I had supraventicular tachycardia about two years ago. I'm 17 now. The doctor told me that it should go away on its own in a few years; he said by the time I'm 19 or 20. I don't do much moving around how because if I do any activity, my heart goes crazy. I quit smoking and all that stuff, and I can breathe better, but that's about it. The simplest things set my heart off. It's not as bad as it was because I have kind of learned to deal with it. I am now pregnancy and afraid that I'm going to have a heart attack or something.

Thanks very much for this very helpful information. In 2006 I had what I thought was indigestion which seemed to respond to magnesia. It lasted on and off for 4 days but was continuous after swimming several lengths. After a bad night my wife called Emergency. It was a heart attack and two stents (angioplasty) were fitted. In July 2009 I thought I was having another attack and went to Emergency. This time it was tachycardia but I spent 4 days in hospital to check stents were OK etc. I have had 2 further attacks but successfully practiced vagal massage. I will give up strong coffee!

My supraventricular tachycardia was treated with I.V. Adenosine. I have 2 - 3 episodes annually. Last one was this weekend. Normally I'm automatically given O2, this time I wasn't. Adenosine is a horrible drug, just for several seconds I feel terribly distressed, it's hard to explain!

My SVT first became evident 30 years ago, age 16. I did not bring it to my Mom's attention as it would self-resolve rather quickly. In my 20's during the first physical checkup in years I was found to have a murmur (turned out to be another issue, a bicuspid Aortic valve) I did decide the "fast heart at time" was worthy of sharing. In getting a 12 lead ekg things looked fine. I don't think Holter monitors yet existed so I was told to pop in Emerg sometime when the fast rate was occurring. Eventually a tracing was done, but no treatment as I could control it via Valsalva maneuver. Now in my mid-forties I have found the SVT's occurring more frequently and could no longer convert on my own. After a few episodes of running off to the ER & getting Adenosine I asked my cardiologist (who I was having regular check-ups for the valve issue) what could be done. I was then put on a calcium channel blocker and consulted to a cardiologist that does electrophysiology studies. The med I was on in the meantime did most certainly cut down the episodes frequency & duration but made me feel subdued, and less energetic. Just yesterday I got the electrophysiology studies & cryoablation. I was out of the hospital by evening & feel good today. I do hope I am done with SVT's for good as they were getting rather interruptive to my life.

I developed PSVT at age 40. I have 2 to 3 episodes a year with my heart rate at 200-220. If I forcefully cough several times as it begins, it usually stops. But if not, I lie down and I place a small plastic bag filled with ice on the side of my neck. This stops mine in 15 to 20 minutes.

I began having rapid heartbeats after having 2 ablations one lasting 5 hours the other 7 hours. Then the rapid heartbeat began which I didn't feel but felt very tired. I was put in the hospital for a few days and put on Sotalol 80 mg. 2x daily and have felt fine since then no problems at all.
