u/Dhatheia7

I woke up this morning at 5am to my watch vibrating intensely and my phone starting to connect to 911 because of a loss of pulse detection.

Now I'm trying to figure out if it was some kind of malfunction or if I had a cardiac event.

Does Fitbit keep a record of this? My heatrate chart looks normal and I can't find any way to see data on this.

Edit to add: there's almost zero chance that I slept on my arm - I sleep on my right side, wear my watch on my left wrist.
