Hey. I know what you are going through. I have episodes everyday myself. I just had my first ablation and it was a major fail. Now, five days later, my heart rate has gone up tremendously. I had an "attack" today and I thought I was going to die! Doctors would tell me it's caused by anxiety and they told me this for 2 years up until recently. I am being treated for SVT and possible cardiomyapathy.
Honestly, having an ablation is scary. I was awake for the whole thing, and ever since I have had it, my heart has gotten worse. But do what you think is best. Good luck
