The results are here from my third and final time wearing a heart monitor since the ablation fifteen months ago. They’re “normal” and “100% Non-AFib.”
There were quite a few instances during sleep when my pulse dropped to 42 bpm. Another effect of being a former marathon runner. Which was also the likely cause of the persistent AFib I no longer have.
A slow heart rate isn’t always a concern. For example, a resting heart rate between 40 and 60 beats a minute is common in some people, particularly healthy young adults and trained athletes. It also is quite common during sleep.
