Hello, I'm new to this group and already finding it very helpful. I have had a successful catheter ablation which lasted from June last year until a few weeks ago when I went into atrial flutter. I have just been started on Amiodarone, this is the third day of taking 200mg 3 times a day but my heart rate is still 147 is this normal? Does it take time for the med to kick in? I'm feeling very anxious which doesn't help and don't know if I should be going to A & E or not. I had a cardioversion last week and have another one booked for next week.
