HRM 200

First of all you have to find whether and when the HRM was really used. If you see some gaps in the Respiration Rate, then the HRM was not connected reliably (perhaps too loose, or dry electrodes). Even better, export the activity and inspect it with Fitfileviewer.com, comparing the charts for Heart Rate, Wrist Heart Rate, and External Heart Rate - that will show you which of them was used at which time. 

Unfortunately I didn’t have the watch on my wrist I put it on my handlebars when I race, I will do this next time though if it happens again take the watch off and put on my wrist

Can you post a link to the activity? It may reveal some clues anyway.

Ya you bet, here it is https://connect.garmin.com/app/activity/22987899316 thanks!

Unfortunately, I do not see much in the data, since there is no HRV (or breathing rate) data included. However, since you did not use your watch, the signal comes from the HRM, and the most likely reason is either the strap too loose, slipping away, or dry electrodes. Try using an ECG gel, and tightening the strap a bit more.

Thanks for looking anyway, I put the data into excel and when I divide the hr by 1.5 it basically lines up exactly with what I would expect. I’m thinking the also got locked onto another part of the hr wave, Im wondering if I was too sweaty cause I wore it under a chest protector, and was soaked.

Too wet (unlike too dry) should not be a problem. You can use the strap for swimming too, so it is designed for such conditions.

Same issue here, look at https://connect.garmin.com/app/activity/23485769660  https://connect.garmin.com/app/activity/23511178552 First time the dealer change the HRM200 and strap, no change :-( (medic say all ok )
