There is a slight warning, about 5 seconds where you can hear a "whining" sound as the device charges up. It's not very loud though I've heard it being in the same room as patients. I could see it being missed if you were doing something loud/active.
The reason there isn't more warning is that you want to shock VT before it degenerates into ventricular fibrillation, which is much more serious.
Your question about falls is a good one and it comes down to how much of a trade off you strike with risks of VT/VF vs risks of the shock.
