Additional
ECG
Placements
The
B
‐
Alert
ECG
algorithms
rely
on
peak
to
peak
measurements
to
compute
the
beat
to
beat
(and
second
to
second)
Heart
Rate.
The
ECG
signal
is
robust
and
the
sensor
placement
is
somewhat
flexible.
BIOPAC's
recommended
placement
is
to
have
the
Left
(
bLue
)
ECG
Lead
on
the
lower
most
rib
and
the
Right
(
gRey
)
lead
on
the
right
collarbone.
Alternative
ECG
placements
however
can
be
used
if
the
recommended
configuration
is
not
ideal
for
a
given
application.
For
alternative
ECG
placement,
the
appropriate
leads
must
be
placed
across
the
heart
(
bLue
lead
ALWAYS
on
the
Left
side
of
participant
and
gRey
lead
always
on
the
right
side).
The
adhesive
electrodes
should
be
placed
on
boney
parts
of
the
participant,
where
there
is
little
potential
for
movement
(from
breathing
or
muscles)
which
can
compromise
signal
integrity.
Contact
BIOPAC
for
additional
information
on
alternative
ECG
placement.
