It
is now becoming clear that the baseline level of cardiac vagal
tone and vagal reflexes can be used
for clinical stratification of prognosis after heart attacks.
A crude method of quantifying the baroreflex-induced variation
of heart periods is currently in use in cardiology and it
involves the calculation of the statistical standard deviation
of the consecutive heart periods. This method cannot discriminate
against other irrelevant variations in heart periods such
as those caused by hormones or temperature changes. The NeuroScope™
quantifies vagal reflexes and measures baseline cardiac vagal
tone specifically, therefore would be an ideal instrument
for screening and community-based practice of cardiology.
