@veronica0127 It is exceedingly common, and normal, for an ablated heart to have an elevated resting heart rate for up to a full year after an ablation. Most hearts revert to their approximate former rate after a few weeks, a few months at most, but some patients report taking up to a year for this to happen. However, you're asking about an exertion rate, and that's different. You may not have known or seen what your former walking HR was, but your quoted rate is not at all surprising. In fact, I would be worried if you'd say you go out for a walk and your HR barely cracks 100 when climbing stairs or hiking up hill. THAT....would be worrying. Your rate is perfectly normal, expected, and even desirable...you WANT a reactive heart keeping you well oxygenated and nourished through rapidly circulating blood.

On the other hand, if you had reported that you go out for a neighbourhood stroll and your HR typically runs up to 145, that's probably not a great sign for heart health. It's too high...probably...and you should see a cardiologist. I say 'probably' because we're all different, and our hearts are all different, and exercise HRs are different. A cardiologist might find that you're perfectly fine and your heart likes and wants to run that high a rate when you're 'strolling'. What'reyuhgonnado?

To hopefully help to allay your fears even more, with another perspective: 'normal HR' range runs from 60 all the way up to 100 BPM. Yes, it's true! Some normal hearts, no cardiomyopathy, no rhythm defects, no valvular defects.....like to run normally at 95 BPM....at rest!! So, if you're walking at a reasonable clip and your monitor shows 115, that's a pretty safe place to be, and you should be reassured. 115 at rest? That's when you know you have an arrhythmia going on.
