5) In the
ECG and Phono Options
area, complete the following, as required:
•
Select each connected option including,
ECG Exist
,
ECG External
,
Phono Exist
and/or
Phono Filter
.
•
In the
No. of Periods to Store (auto-locate)
field, enter the number of heart cycles (1-4) of the
frozen image that will be displayed in the multiple screen/split screen when in freeze mode.
•
In the
Standard Systole Time (msec)
field, enter the default systole time, which enables
cineloop synchronization.
•
In the
Store time without ECG (msec)
field, define the default length of a cineloop when there
is no ECG trace.
•
Select the
Analyze only Systole
checkbox to place markers only on the systole portion, for
synchronization and analysis purposes.
•
Select the
Advanced Synchronization
checkbox to enable the use of a special
synchronization algorithm. This algorithm allows non-linear stretching of the time base to
compensate for non-linearity of the heart cycle between the resting HR and elevated HR.
•
Select the
Special Systole Colorization
checkbox to enable the function of systole and
diastole colorization, if required. This function will present the systolic ECG signal in a different
color from that of the diastolic ECG signal.
Note:
The default factory setups are seen in
on page 3-45. However, the user may
want to set different values and presets.
