I am a 33 year old woman who has had issues with SVT(heart arrythmia) in the past. I had ablation surgery for it 6 years ago and I thought it was gone for good. Since then I have had spasms in the stomach solar plexus area which cause intense anxiety for me and I can't figure out what it is. I feel like my heart skips and I feel faint. Any idea what this could be??
