Abstract
Exercise testing as a part of the Cardiac Rehabilitation
(CR) has been reported to be beneficial for patients
with Coronary Artery Disease. Abnormal heart rate during
the recovery phase of the exercise has been proven to
contain
information concerning patient's clinical status. Many
studies
also denoted the significance of the first two minutes of
the
recovery as a predictor of mortality. In this study,
employing
signals recorded from patients during a CR exercise
program
at home, instead of a stress test in a clinical
environment, we
analyzed the HR signal toward the understanding of the
balance
of sympathetic and parasympathetic nervous system at
the start of the program and after its completion.
Features
from time and frequency domain, already used for the
evaluation
of the exercise, were implemented. As an amelioration of
the patient's status is detected based on these features,
while
the CR program proceeds, we used wavelet domain features
in
order to understand the modification of the sympathovagal
activity with regards to the evolution of the recovery
phase.
Unlike the already used features, the wavelet domain ones
are
able to reveal information concerning the modification of
the
Autonomous Nervous System balance during the recovery
which is achieved as the CR program proceeds, as well as
the
importance of the 2 first minutes of the recovery, even
in a CR
program performed at home.
