The cause is unknown but I don't think I had it before my EP study. I am short of breath and extremely forge
tful, again was not like that 8 weeks ago. Doctor thinks it is due to my AVNRT that I have. I can't walk 20 feet without symptoms. I went for first ablation due to SVT's a few times a year and now I am practically disabled. Going for second ablation with new doc. Just wondered what the lack of blood flow to this area of the heart typically means? Thank you!
