In this article, we carry out the study of
the energy contribution of theRRsignal in
the three frequency bands (LF, MF, and
HF) during PTCA. Furthermore, variables
based on instantaneous frequency
and on group delay computed from RR
signal in the three frequency bands are analyzed.
All these variables are calculated
by applying the Choi-Williams distribution
(CWD) to the RR signal. The purpose
of studying these variables is to provide a
punctual location of the energy in the
time-frequency plane, since this can allow
different kinds and locations of coronary
lesions to be distinguished.
This work was partially supported by the grants CICYT (97-0945-C02-01) and FEDER (2FD97-1197-C02-02), both from the Spanish Government. |
