Had cathetor ablation following a 189 heart beat which I could not control (prior to that over a number of years had, say 120 beats - I could stop by holding my breath a few times and it would disappear). Eight months after the cathetor ablation I now have a thumping feeling (front & back) most of the time -sometimes quite fast - is there any way to stop this - I am not 'keen' to go & have another ablation. Thank you.
