I am glad I made the decision to try Tikosyn before an ablation. I know sometimes more than one ablation is necessary especially when you have hcm. I definitely need to be in sinus rhythm. Rate control did not work and I had 6 months of heart rate spiking as high as 165 to 175. Rate control meds did keep it partially under control. It wasn't always high but most days had many hours with rate over 120. Not fun. The hospital stay to load Tikosyn was easy. Just hung out in my street clothes, visited with nurses, read, played games with my daughter. Had blood work done every morning and ecg after each dose. Did end up having a electric cardioversion on last day as meds did not convert me. However, after 9 weeks, I am still in sinus rhythm and feeling good. Had visit with my cardiologist in Oct. and will see EP in December. Return in year to cardiologist and hoping for same or to released by EP unless Tikosyn stops working. Good luck to you. Don't be afraid to try Tikosyn.
