So it watches your bloodpressure or something?

I figured it was the jerking-around. Maybe it looked to the watch like she had fallen down.

It watches the heartbeat, probably arrhythmias specifically. You can't monitor blood pressure with just a watch. You need a blood pressure cuff for that.

The Apple watch can look at blood oxygen levels too which might have been what triggered the alert.

Does it watch heartbeat via the gyroscope? If so then that's a darn sensitive gyroscope.

Via an optical sensor that can perform photoplethysmography.
