Flecainide Acetate side effects

I am a 39 year old female and I had an atrial ablation a 2 years ago, then 4 months later the a-fib returned and I went on the flecainide. I have nw been on the flecainide for more that a year 150mg(am) and 100mg(pm) and the shortness of breath and flutter has returned. Has anyone else had anything like this happen to them?

I have had A-Fib for approx. 6 years. I am a 61 yr old male, and have taken Flecainide for approx. 2 years, along with Diltiazam. I have loud ringing in my ears. I often wake up in the night with a very rapid heart beat (in normal rythnm). During the day I'm not bothered much by a "pounding" heart beat, but am at night. I still go into A-Fib periodically with this medication, and it usually last 6 to 8 hours before going back on its own. A-fib attacks vary--I may go several weeks, then have problems 2 or 3 times a week.

I have had AF for about three years. A year ago, I was in A Fib for about 3 months and decided to try flecainide. In four days my heart went into rhythm and stayed there for 8 months. A few days ago I awoke to a racing but regular heart beat of about 100-105 BPM. This has continued for 3 days and my doctor has recommended that I continue at an increased dosage. I seriously wonder if this is a side effect of this medicine.

I been on Flecainide for three weeks now for arrythima(SVT). I haven't really felt any side effects, sometimes I do get a stomach ache. I sometimes feel flutters, but not near like I use to, I feel like this medication keeps my heart rate normal, and it keeps me from going into an SVT attack, where my heart is racing like crazy. Hopefully, this medication will continue to help me, because its so scary to have your heart race!
