Maybe you should quit while you're ahead, Bill.
 
0.93 Hz is 930 mHz, not 93 mHz.   :)
 
At 93 mHz, I suspect you'd be flat lined with spikes (probably very small
ones) just over 10 s apart. I don't think that would be a sustainable
condition.
 
To use a British expression, you would really have a dicky ticker.

That's a helluva fast pulse. 56 Hz is 56 beats per second, not per minute.


Ooooh!  You're so right.

Sorry about that. I was trying to be cute when I tacked that note onto my
previous message, hurriedly, at the last moment, and  without sufficient
thought. 

I had never before thought about heart rate in SI but in a flash of
misguided inspiration, I recalled my blood pressure machine giving me "56"
for my pulse rate. Since our discussion had been about measuring frequencies
in hertz, I thought about adding a note about my pulse rate in hertz as
well. I then quickly jumped to the incorrect conclusion that the "56" would
be 56 Hz. Of course, 56 Hz is 56 beats per SECOND and my BP machine was
really giving me the rate in beats per MINUTE. (The 56 beats per minute
would translate to 0.93 beats per second or 0.93 Hz or 93 mHz, not 56 Hz.)

It just goes to show, that one cannot try to be too "cute" without
appropriate care for correctness.

Thanks for catching my mistake. It's one I won't make again.
