My husband has a persistent a-fib. He seems to be getting weak and sluggish again. He had 2 cardio versions and an ablation in April this year. Did seem to recover and gain strength and stamina until yesterday. Now weak and slow walking. Dr. Wants to put on tikosyn, stronger than Sotalol. Sounds good to us, though we are wondering is there something else he can do to get this heart beat regulars again. He is 84 years old and healthy otherwise. Thank you.
