Recently,
cardiovascular
disease
has
risen
sharply
due
to westernized
food
habits
and
an increasingly
aging
population.
According
to statistics
reported
in 1998,
the
leading
cause
of death,
respiratory
disease,
accounted
for
23.9%,
and
ten
times
as many
people
suffer
from
heart
disease
as 30
years
ago
and
seven
times
as many
compared
to 20
years
ago.
Consequently,
most
hospitals
devote
their
efforts
to offering
high-quality
medical
service
and
educational
programs
for
treatment
of cardiovascular
disease
with
high-tech
equipment
and
competent
medical
professionals.
The
electrocardiograph
(ECG)
records
electrical
signals
from
the
heart
via
a series
of electrodes
attached
to the
chest
to diagnose
cardiac
activities
such
as arrhythmia,
hypertrophy,
infarction,
and
ischemia.
The
24-hour
electrocardiography
is used
to observe
patient’s
cardiac
statistics
such
as heart
rate
and
electrocardiogram
followed
by computer
analysis
of the
recorded
data
which
counts
ECG
complexes
to identify
cardiac
arrhythmias
and
ischemia.
However,
these
24-hour
electrocardiography
systems
are
not
available
domestically
so they
solely
depend
on imports.
