Cardiology 6-21
2. In apical two-chamber view, measure the following parameters:
Left ventricular endocardium at end-diastolic, and set the long axis, the EDV(A2C) is obtained;
Left ventricular endocardium at end-systolic, and set the long axis, the ESV(A2C) is obtained;
3. In apical four-chamber view, measure the following parameters:
Left ventricular endocardium at end-diastolic, and set the long axis, the EDV(A4C) is obtained;
Left ventricular endocardium at end-systolic, and set the long axis, the ESV(A4C) is obtained;
4. If height and weight have been input already, SV, EF, SI, EDV Index and ESV Index are
calculated.
5. Using touch screen knob to select HR source: ECG or input.
The CO and CI are calculated automatically.
