Ok, thanks. I wasn't sure I was in the right area.
I'm sorry about this. Perhaps you should ask your question at the expert forum not in the community. Community is for patients supporting each other; expert forum is for getting the technical questions answered. Maybe it would be better if there were an internet site for a community of experts to discuss heart issues. It would be very interessting to listen and/or read these discussions. Most of us in this community, however, can only relate to what it is like to have a debilitating arrhythmia. We dont have the type of expert opinion you are seeking here.
kindest regards, Bromley.
