Color Map: The usual used color map for cardiac issues is the "Jet Invers" map, but you can also
choose "Hot, Cool or Grey" maps. To remove the colors from the map, click "Off". The isochrones
will remain only.
Contour: The drop down menu is for changing the color of the contour for the isochrones into
"Black, Jet, Hot, Cool and Grey". Or you can remove the lines with "Off". Adjust the number of
the contour lines from the numeric box beside; up to 100 contour lines are possible.
A rrows: The feature is not yet implemented in this version of Cardio2D+. As soon as it will be
implemented, you find a Read Me on the MCS web site, where you will be able to download the
new version of Cardio2D+.
Minimum / Maximum: You have to define the minimum and the maximum of the scale of the
color map. That means, you define the time frame in which the excitation pattern are displayed in
the color map. Usually you start with zero in the minimum, that is the pacemaker. The excitation
pattern will run from the pacemaker over the map to the maximum. The widest selectable time
frame for the color map spans from 0 μs in the minimum to 10000 ms in the maximum. To change
the colors of the map, please use the first drop down menu "Color Map".
Auto: Click the check box "Auto" in "Maximum" option. The "Minimum" is zero, you are not
allowed to modify it in Cardio2D.The Cardio2D program automatically finds for the maximum
of each heartbeat, and adapts the scaling of the color map. It is recommended to use the auto
scaling function.
Size (W x H): You can modify the size of the color map.
Interpolation: Interpolation is a mathematic method to calculate missing information between
two points of a line. The bilinear interpolation uses four points of the nearest vicinity to calculate
the interpolated point. The bicubic method uses eight points to calculate the interpolated point.
The interpolation method of the "nearest neighbor" uses the mean value of four or five points
to calculate the interpolated point.
Show Electrodes: Click the check box for displaying the black circles indicating the electrodes
in the color map.
