Garmin showing unusually low heart rate during intense workouts

[Teddlesisagoodboy]

Hi, has anyone experienced this? I'm not sure if it's a fault with my garmin but a few times during very intense workouts my heart rate seems to have dropped very low. Like Lower than my resting heart rate. My resting rate is about 58,but this drops to about 40. What could this be? Has anyone else experienced this?

That seems an error if it's so low in an intensity activity. Is it secured properly? Have you tried it on the other wrist ?

Do you feel any symptoms when this happens or just notice it on the watch? Do you see it at the time or afterwards? Checking your pulse (first two fingers on your wrist - count for 15 seconds and times by four) would be a good way to check, but suspect it’s a gizmo error if no symptoms

Have you manually taken your pulse to compare when the watch alerts to a low heart rate?

No, only once I realised it was happening and the watch seemed to be on properly, touching the skin. I didn't think to take my pulse and then it went back up. I've just noticed on two older recordings it appears to have happened too.

I've had some periods at night where the garmin doesn't register HR at all. I clearly must move into a certain position to trigger it as I am still alive !
If you are not feeling faint or dizzy in the workout then I'd try adjusting strap and or switching wrist and not to worry about it
