I know.=20

I just wanted to give info, that a heart rate of 60Hz is absolutely
impossible.=20
Standard heart rate is 60 /*MINUTE* equals 1Hz.=20
Max. frequency under stress conditions can be assumed with 210/Minute =3D
about 3,5Hz.

All this for humans.

If your are examining animal's hearts the values can be much higher. Small
mice can have up to 500/minute. Elefants in the region of 25/minute.

Important are details within the cycle. At 5Hz rate you won't get needed
resolution with 60Hz filter.
