I'm a 16 year old female and I went under a catheter ablation for AV mode reentry tachycardia disguised as afib. Since then I've been experiences lots of PACs. In the past week they have become more frequent, I would say hundreds a day. I'm worried about it. Is this normal? Am I going to have a heart attack for anything? I have high anxiety so anything going on with my heart really scares me
