Fig. 2

The figure shows an E-wave from pulsed-wave Doppler measurement of the flow across the mitral valve. The solid white line (right panel) shows the curve fit of the PDF method whereby the mathematical formula describing a damped harmonic oscillator is fit to the contour of the E-wave, thus generated the PDF measures. Analysis was performed using the freely available software www.echoewaves.org
