Coronary Artery Spasm Question

[Bromley]

I had an ablation in 2004 for left free wall WPW and was left with some VT. My VT typically presents after I have been training to run long distance and am beginning to overstress myself, either over several days, or upon unusually longer than normal distances (for me, this limit is now ~10 miles, post ablation). The first documented case of short run VT occured at rest while I was laying on my left side.  I felt something snap, a snap of pain that I am certain was not caused by a heart beat, that was followed instantly by a run of VT.

Aside from this, I had in 2004 an angiogram that came back normal. At the time I was recovering from an ablation and had what I felt were angina like symptoms. From 2004 til present, I have experiences occassional VT as I mentioned above, and some episodes of sharp pains coming from the left side of my chest. These episodes occur on and off for several days and last under an hour each time, then go away entirely until the next episode, perhaps several weeks later.

I never experienced these symptoms prior to my ablation. I certainly never experienced tachycardia at rest prior to my ablation, and I never had tachycardia at rest that made my woozy, i.e. like my VT does.

The thing I am wondering about is 1. whether this ablation could have resulted in an injury to a coronary artery. I believe the ablation attempt was made at the mitral annulus, taking the transaortic approach through the aortic valve into the left ventrical, with the probe turned around and pointed towards the underside of the mitral annulus (in other words on the left side of the heart from inside the left ventrical with the probe pointed upward towards the underside of the mitral valve). My thinking is that this is a difficult manuever that could have led to coronary artery injury. 2. whether anyone within the reach of this post has run into a similar situation and what they did about it. 3. whether any brainy person out there could help me brainstorm some ideas about what testing is done, appropriate specialist to see, etc.

I realize this question is technical, but I will take all opinions, medical and non-medical.  Thanks in advance for any input.

Thank you for replying.

Aylish28, I think it is interesting that  a chemically induced cardiac stress test might be used in the diagnosis. This is something I was unaware of and I have not had one of those yet.  I will definitely ask about it the next time I see my cardiologist.

jyant, I think you may have that right. Some of these heart rhythm problems seem to be real brain teasers, and there aren't always a lot of quick fixes for people on this thread (although some do come out OK).

However, one thing I have learned when trying to solve a puzzle is to be persistent.  Sometimes we can solve em over a long haul. For instance, it did take me over twenty years to get the first recording of my SVT...  at this point that whole problem is pretty much behind me now.

Your like one of the most logical people on these threads, pretty clear you think a boo boo happened or just the nature of the beast (difficulty of ablation).

Life change it up...no quick fix

tests were ecg and also chemically induced stress test
