Automatic Determination of Systole and Diastole

Automatic
4–40
The system can be programmed to automatically determine the
cardiac phase as systole or diastole. The parameter in the
Setup/Preset Program Sub-Menu page 3 used to make this
selection is:
Diastole/Systole Determination : Manual
The auto determination of systole/diastole can be fine tuned
using the following parameters also found in Set Up/Preset
Program page 3:
R Delay Time of End Systole Prior Edge : 0–2000msec
End Systole Period from Prior Edge : 0–2000msec
If Auto is selected, the determination is made by comparing the
displayed B-Mode or M/D Mode image frames with the R-point
on the ECG wave. Therefore, 's' for systole and 'd' for diastole
is added automatically to the measurement or calculation name.
If phase cannot automatically be determined, the system
displays the following message:
"Diastole ('d') or Systole ('s') ?"
Entering 'd' or 's' are the only two acceptable inputs.
's' Erases the message, recognizes the
phase as systole and adds a 's' to the end
of the measurements or calculations.
'd' Erases the message, recognizes the
phase as diastole and adds a 'd' to the end
of the measurements or calculations.
The user will not be able to perform measurements of the
opposite phase until the next image change is made.
