It also is above the cadence (and above my max HR). Static from the vest top? It was a hard workout on a hot day, and after 1 mile I'm very sticky, but I didn't feel I was dying so I assume that it's some bug in the reading somewhere. http://www.fetcheveryone.com/gallery-showphoto.php?id=82645

Chrisull Jun 2016 4:24pm, 6 Jun 2016 8,982 posts	0 Chrisull Paul - as far as I'm aware I don't have arrythymia, I assume there would be symptoms other than erratic readings. I never used to get that on my HRM, but last few runs it has started to happen, I used to get the opposite - erratic contact early on, then consistent readings. It is right that it happened when I increased pace, perhaps the contact becomes loser and bangs on my chest?

A rapid (almost vertical increase) followed by a period of high HR then a vertical decrease.
