4-2-2. Items of Special Note Description of left ventricle volume measurement The following description is applicable to the 2B mode using the 2B Mapping function. When using 2B Mapping, you can display end-diastolic and end-systolic images for the same cardiac cycle. Use this function to measure the volume of the left ventricle. Be careful of the following points when performing blood flow measurement related to Doppler. Angle correction operation: Before starting Doppler measurement, perform angle correction. [Remark] If the Doppler angle exceeds 20 degrees, the accuracy of the measurement results may be adversely affected. For this reason, we recommend that you project the beam parallel to the blood vessel as far as possible. Re-using existing measurement values: You can re-use existing measurement values, so there is no need to repeat the same measurement. A description of the layout and functions of the switches and keys used for measurement is given in the section entitled, Description of basic operations for, Section 1. “MEASUREMENT FUNCTIONS”. The measured values of the blood flow values obtained using this equipment are the absolute values displayed on the observation monitor. They are controlled as positive and negative values for the purpose of calculating the arithmetic index.If the display of each measured value in a report is set to "Average" in a preset, the positive and negative values are added together and displayed as a mean value. Consequently, when performing multiple measurements of blood flow on the blood flow waveform drawn using the color Doppler method as a guide, use identical recording conditions (forward and reverse flow directions) for all of the blood flow waveforms in order to correctly display each of the arithmetic values arranged in the report.

Area-Length measurement
Measure the left ventricular chamber area (LVLA) and the left ventricular long-axis length (LVL) from the crosssection of the apical two-chamber or apical four-chamber using the Area-Length method, then obtain the left ventricular volume (EDV, ESV), stroke volume (SV), cardiac output (CO), ejection fraction (EF), and other indexes.

[Remark] When you use the 2B Mapping function, you can display end-diastolic and end-systolic images for the same cardiac cycle in the 2B mode.
<Operation method> (1)
Display end-diastolic and end-systolic images for the same cardiac cycle in the 2B mode.

Trace the left ventricular inner membrane (LVLAd) at end-diastolic, and press the MARK REF switch. →
The trace closes, and the long-axis line (LVLd) appears.
[Remark] You can set the left ventricular long-axis (LVLd) using the trackball.

Press the + switch. →
The + mark appears and also appears at the bottom of the screen, so trace the end-diastolic left ventricular inner membrane (LVLAs) in the same way as in step (3).
[Remark] If an ECG is not displayed, press the + switch. A dialog box for entering the heart rate appears, enabling you to enter the heart rate from the keyboard. (5)

Simpson(Disc) measurement
Measure the left ventricular chamber area (LVLA) and the left ventricular long-axis length (LVL) from the crosssection of the apical four-chamber or two-chamber using the Area-Length method, then obtain the volume (EDV, ESV) of the left ventricle regarded as the sum total of 20 circular disks intersecting the left ventricular long-axis at right angles, the stroke volume (SV), cardiac output (CO), ejection fraction (EF), and other indexes.
