Chapter 9 Cardiac Measurements and Calculations
The cardiac examination is usually performed in the B mode, B+M mode or PW mode.
Press Transducer, select the desired probe model and the exam mode Adult Cardiac/ Pedia
Cardiac, and then press OK, or double click on the exam type.
The result of ventricle volume measurement is more exact in two-dimension. You can get the
two-dimension heart image of end diastolic and end systolic exactly and conveniently in the B+M
mode. So we suggest that you do the cardiac measurement and calculation in the B+M mode.
