I have been taking Flecainide for 2 years and am now having frequent runs of tachycardia which my cardiologist says is Atrial Flutter caused by Flecainide changing AF signals into AFlutter. I have no AF - just short runs of rapid, regular beats of 130bpm now coming almost daily.
My EP is aware of these runs which happened only a couple of times in 18 months to start with and described them as not a separate arrhythmia but the result of taking Flecainide. I am now waiting to see my EP again and really fear that anti-arrhythmic drugs all may have the same effect - so I'm feeling a bit long in the face today.
Has anyone had this side effect from Flecainide and how was it resolved?
