6.3 Cardiac Measurement Tools
The system supports the following cardiac measurements:
NOTE: 1. Measurement tools mentioned below are configured in the system. The application
measurement packages provided in this system are generally different
combinations of measurement tools. For more information about package preset,
see "2.4.2.2 Application Measurement Preset".
2. The heartbeat of the traced spectrum in VTI measurement should equal to that is
preset, otherwise the obtained HR (Heart Rate) is incorrect. See "2.2 Measurement
Parameters Preset" for relevant preset.
3. Some application items in the measurement preset library (and matching list in
result assignment) are displayed different from that in the measurement menu and
result window.
In preset library (and matching list in result assignment), the item is followed with
the word indicating the mode or location. Such as LA Diam (2D) means that the
item is measured during 2D mode; LA Diam(LA Vol A-L) means that the item is
contained in a study named LV Vol(A-L).
