Left ventricular inflow propagation velocity: Comparisons between pulsed wave and color M-mode Doppler echocardiography

Abstract Sixty-six participants (age 58 ± 16 years) were included for evaluation of the relationship between color M-mode and pulsed wave Doppler left ventricular inflow propagation velocity (LVIPVcmm and LVIPVpw, respectively). LVIPVpw was measured through the application of the range ambiguity phenomenon, and LVIPVcmm was obtained by manually tracing the first aliasing velocity during the early filling. The variability for LVIPVpw measurements was significantly less than that for LVIPVcmm measurements. There was a significant correlation ( r = 0.678, P (J Am Soc Echocardiogr 2002;15:1461-7.)
