I have paroxysmal AF and had an ablation last Nov after a few nasty episodes of fastAF and cardioversions. I am taking bisoprolol and warfarin. From time to time I have episodes of what I call palpitations.They come and go. I don't know whether this is AF showing itself differently or whether they are ectopic beats. Is there a good way to tell? I've has ECG's but unless the palpitations are happening at the moment of the ECG nothing shows .Any pearls of wisdom on this? I'm a worrier !
