My Atrial Tachycardia (SVT) was gone for a year and a half post ablation. It returned almost a year ago. In that year I had a failed ablation (couldnt induce). Have tried Metoprolol, Propranolol, Cardizem, Flecainide, Norpace, Rhythmol. Saw a Naturopath and tried Arginine/Taurine/Hawthorn. EVERYTHING has given me unbearable side effects. And I am still stuck with the Atrial Tachycardia. I have a second opinion with a different EP on October 5th. Hoping for the best. Feeling sad and discouraged.
