Re: Bring on the stupid
Registered nurse with a lot of telemetry experience here: I agree with some of the other comments. NO ONE'S ECG is consistent enough to use as any kind of login or a password. The only perfectly consistent ECGs one ever encounters are in the lifesaving and telemetry classes, where the ECG is computer-generated. The heart is not a mechanical device, churning out identical beat after beat after beat, at least not in humans. It tries, but it's not a looping sampler. ;-)
This is one of the nuttiest ideas I've ever heard of for using medical info. Someone missed the critical thinking course on this one.
