The best ECG signals can usually be picked up by placing
the round end of the Actiwave Cardio unit in a position
midway between and below V1 and V2.
electrode can be placed at V4 or V5. A position on the
upper chest shown in the diagram below can also be used.
This may be either more or less acceptable for female
users depending on their breast size.
For good accurate measurement of activity and body
position the cable needs to be placed with the cable exit as
near the horizontal as possible. If necessary use a small
piece of tape {Micropore or similar} to hold the cable
horizontal. This will avoid unnecessary rotation of the
sensor in situ. The main body of the device should be
located close to the centre line of the chest (see photo).
The acceleration output of the Actiwave cardio is labeled in
X, Y and Z axes, with meanings as described and
illustrated following. Note that the software can also be
made to produce text annotations of the body orientation
during steady non-moving periods. This may be easier to
interpret than the three acceleration numbers.
