2 years ago I had a "cryoblation in my heart" for SVT (AVNRT) the extra circuit was too close to the natural pacemaker which is why they did the cryo rather than heat ablation. I was okay up until recently when the SVT symptoms returned. Been having severe cramping on the left side of my chest as well. I have had 2 SVT episodes in the past month. Went to the dr. yesterday, did an EKG which said, "Abnormal" PROBABLE INFERIOR INFARCTION, AGE UNDETERMINED; Q WAVES IN INFERIOR LEADS AND T WAVE INVERSION ALSO PRESENT. I have never had an abnormal ekg before this. I work out regularly, eat healthy, don't drink or smoke, am 35yr old female w/ normal blood pressure. I do have a lot of stress in my life. I am seeing the cardiologist today but am curious as to these recent findings and what could be going on.
