I was put on tikosyn last week and have already had an episode that lasted 90 min and my heart rate was 140-150. Is the necessary to go to the ER or just wait it out? I have been to the ER 5 times this year and am very upset and discouraged. My cardiologist said I am headed for an ablation. I don't feel good at all on this med and would very much appreciate some feedback. Thank you very much
