I'm a first-timer and have a couple of questions. I am told that I'm in the persistent range of AF. I began loading up with Amiodarone three weeks ago..600, 400 and now 200mgs. I feel much better, still lots of flutters though that I feel at night. However my heart rate went from 100-110 up to 120-130 and has stayed there for the past three weeks (my normal rate was 62-68). I have been taking bisoporol 10mg beta blocker for two months which doesn't seem to help. I have 53 left atrium measurement....up from 47 nine years ago.
Does heart rate increase with amiodarone? Knowing size of LA, can another antiarrythmic be used?
It seems that the AF diagnosis is more of a symptom and severe LA hypertrophy is the diagnosis...any thoughts on that? Many thanks.
