[G4] OT, Dead APC backup

[sr ferenczy]

average adult heart rate is about 72 beats per minute, or 1.17 Hz. and 
the sinoatrial node (the "natural" pacemaker) releases a signal approx 
72 times a minute to prompt the heart muscles.  this frequency would 
increase or decrease based upon physical exertion.
