Dias Vel. (Diastolic Velocity) Velocity

Sys Vel. (Systolic Velocity) Velocity

Rev Vel. (Reversal Velocity) Velocity

For more information, refer to ‘Doppler Spectrum Measurement Method’.

NOTE

The Auto Trace function is not provided in MV Inflow and TV Inflow.

■ The values of Peak, Acc Time, Dec Time. Ejection Time, VTI, PHT, R-R Interval, etc.

are automatically measured by tracing the Spectral Doppler image. Each item can also

be selectively measured.

- Peak V: Measures the higher velocity value.

- Peak E: Measures the Ventricular Systolic peak.

- Peak A: Measures the Atrial Systolic peak.

- Acc: Measures the time duration when blood flow is accelerated. Dec Measures

the time duration when blood flow is decelerated.

- [E-DT-A] : Measure Peak E,Dec., and Peak A in order.

- Ejection: Measures the time duration by measuring the distance between the

Aortic Valve Opening and Aortic Valve Closing.

- VTI: Calculates the value using the formula of VTI = Sum of V

∆t after tracing

the Spectral Doppler image.

- PHT: Calculates Half-Time using the Pressure gradient value obtained between

the E point of Valve and the baseline.

- R-R Interval: Measures the distance between consecutive R waves on the ECG.

■ LVOT Doppler

Measure Left Ventricular Outflow. Its sub-menu Dia. measures the Aortic Valve

Annulus point in the 2D image.

■ The sub-menus of Plum. Veins are measured as shown below.

- Dias Vel. and Sys Vel. measure the velocity at the diastole and systolic phases.

- A. Rev Vel. measures the Peak Velocity at Atrial Reversal.
