pulsed Doppler

pulsed Doppler

a type of Doppler device that transmits a short-duration burst of sound into the region to be examined. The Doppler-shifted signals are processed from a limited depth range. The depth range is determined by a sample gate whose position and size usually can be selected by the instrument operator.

Aortic velocity-time integral (VTI[sub]LVOT) was measured using pulsed Doppler on a 5-chamber apical view, and VTI[sub]LVOT was measured in 3- or 5-chamber view, with the sample volume placed approximately at 1 cm of the aortic valve.

Mitral E velocity (ME), mitral A velocity (MA), mitral E wave deceleration time (MEDT), and LV isovolumic relaxation time (IVRT), defined as time period between the termination of aortic systolic wave and beginning of ME, were measured by locating the sampling volume cursor of pulsed Doppler in the apical four chamber position at 5 mm above the mitral leaflets tips.
