Hello Fucci, We've had similar experiences. I'm a 74 yr. old man , that had an A V Node ablation Oct. 21 2024, after 6 ablations over the years. I too can't walk long distances without feeling I'm going to faint. My heart rate and blood pressures are always normal. I'm very depressed that this is as good as it gets. Doctors keep saying give it time, but I'm not gettin that much better.
