The Z-Console's ECG waveform display
is fun and interesting feedback of your
heart's actual electrical signature,
called an electrocardiogram (ECG). It's
not as smooth and fancy as the
waveform you would see on expensive,
12-lead medical systems, and it cannot
be used for analysis or diagnosis. It's
just fun to look at.
The waveform display is generated by
the Z-Console's state-of-the art contact
heart rate system, accessed by gently
gripping the contact heart rate pads on
the handlebars. The ECG display takes
the place of the progress display in the lower half of the
screen. Pressing
changes to a normal progress display.

The vertical size (ampli-
tude) of the Z-Console
waveform is NOT indica-
tive of heart strength or
health. This amplitude is
simply an effect of the
position of the heart in the
chest cavity. In most peo-
ple, the heart is tilted to
one side (from upper-right
to lower-left in the chest),
which creates a noticeable
voltage difference between
the right and left hands.
Some people's hearts are
in a more upright position,
which results in lower volt-
age and lower amplitude.
