Here's an interesting issue. I consistently show a significant reduction in heart rate if I have some acid reflux or burping response while I'm running at any pace.
So if I'm running at 155 and this acid reflux happens, my heart rate will fall to 145 for about 10 to 15 seconds and then it returns to 155.
This happens always and shows up in a predictable manor.
Does anyone understand the mechanics of this? Can anyone give an explanation about this?
Thank You
