Pulse monitor on Apple Watch 4

I am noticing two odd things: one is that the watch records heartbeat when I'm not wearing it. And more important, how does the pulse monitor bounce around by 30 points e.g. 52 to 92) within a minute while I'm at rest?? I feel as if the watch is not operating properly

Apple Watch Series 4, watchOS 5

Apple Watch problem with heart rate monitor Is it a common problem that the heart rate monitor stops working continuously after a period of time? I’m doing interval training and it stops tracking for many minutes at a time. I’m considering purchasing a new one but not if this happens with all apple watches.

Heart rate monitor not recording during workouts Hi, I have a series 6 Apple Watch and it has stopped recording my heart rate during workouts. This is happening sporadically during walks, running and while using fitness +. Sometimes, once I realise it is not recording my heart rate I can trick it into doing so by using my Heart Rate app and forcing it to take a reading, which is then recorded on the workout app, but not always. When I check under my watch, the green lights are always on, just not recording my heart rate. I have already made sure that my watch is not in power saving mode in the workouts app and I have unpaired and repaired my watch twice with the same issue still happening. Can anyone help? I’m at the point I think it must be a fault with the watch but wanted to check here first. Thanks in advance

watch lags recording heartbeat during exercises I’ve had my watch for a year (Apple watch 5 Nike GPS) and I work out daily and for at least 10-20 minutes of my 60 minute workouts (broken in multiple segments) the watch doesn’t record my heartbeat. Any suggestions or should I just switch from Apple to something specifically designed for workouts only?
