Thought I would share latest development after my first ablation which took place last November. I did not have any bouts of AF since and felt much better all these past months. Saw the consultant (well, his registrar) on Monday. He advised to stop taking Flecainide and Diltizem but to continue with Warfarin because I had episodes of paroxysmal AF over a period of 2 years. They will fit a ECG monitor on 1 April and then make a decision about stopping the Warfarin.
Asked him about elevated heart rate (62 compared to 48 pre-ablation) and he said this was nothing to be worried about. If anything, a lower HR post ablation would be problematic as this could indicate damage to the nerve and requiring a pacemaker.
I also asked him about exercising as I am a keen & competitive cyclist. After ablation I had exercise fatigue and my GP suggested this could be due to Flecainide and Dilzem. The consultant thought this was possible. So after stopping the meds I went on two bike rides and have the feeling its going better. I also asked about exercise being a potential cause for new AF episodes, via a regrowth of nervous tissue in the heart. He did not think this was the case and did not warn me off strenuous exercise (I know our friend elbows has written on this forum about it). He said there is a small probability of AF re-occuring but is not related to sports activities.
So I will see how it goes, if I can come off Warfarin and if I get back to full fitness.
