“auditory displays”<br />
A healthy heart beat shows subtle<br />
but complex variations with<br />
intermittent, but not<br />
extreme, fluctuations in all<br />
parameters, creating a<br />
pattern that is neither<br />
random nor periodic.<br />
Changes in the mean and<br />
standard deviation are<br />
easily perceived, reflecting<br />
physiologic nonstationarity.<br />
Patches of higher variability<br />
produce clusters of the<br />
tinkling sound associated<br />
with larger interbeat<br />
intervals.<br />
