 WE> I see, since the P-P interval is less than one the 
 WE> reciprocal transformation exaggerates the spread.
 JB> Yes and more familar for most physicians. 
Likely chosen for it's ability to magnify.
 WE> Hm, it's doing more than just checking the deviation of distance(HRi' 
 WE> - HRi) i' = i+1.  It's checking meander.  How conceptually does  
 JB> You got it. 
 JB> 
 WE> this compare with the deviation of the data set HRi? 
 JB> Not sure what you what you mean by this question. 
Deviation of the data set could be all HRi - HRj for all pairs of i,j (ij) 
that make the difference non-negative.
 JB> Oscillation within a plane (x,y).  The plot (x,y) is the

This is getting complicated.  The pivotal point moves from 0 to l and back 
again to 0 and does this in 1/hf.  This is not a free dynamic system in which 
the pivotal point freely slides back and forth according to the inertial 
swings of the pendulum.
Hm, if sf = hf then we'd have zero spread?  
Intriguing little system.  Are the equations of motion useful?
The plot (x,y) is similar to the HR plotting discussed before?  That we are 
measuring pendulum pluses, reciprocal of pulse to pulse interval?
 
 WE> Is this quiescence during or before a VF attack. 
 JB> Before, hence, the reasoning for wanting to explore it. 
The lull before the storm?  That eerie feeling that things are just too 
uiet?
 
 JB> Yep, and that "something" (coming to a standstill) is 
 JB> variability. 
Battlefield jitters from lack of usual enemy activity?  A lack of background 
noise alerting a parent that the kids are up to something she'd had better 
consider?
 JB> Ah, at least with the pendulum example, the plot (x,y) of 
 JB> the pendulum although chaotic is within certain bounds. 
Now as you vary hf how does the spread change?  
Any abrupt changes or discontinuities?
 
 WE> So you're a mathematical literate doctor that would like to 
 WE> do research except for lacking funds? 
 JB> Yep.  BTW, thanks for sending me your thoughts on 
 JB> logical qualifiers.  I printed it out so that I could read it 
 JB> and no, I didn't try to save it to a file .  
Well let's see.  What's your opinion on alternative medicine?
Any comments about the medical system or delivery of services?
... By product of cold fusion is He2, the helium molecule, He-He.
