  • Values are mean (SD). A2, first high frequency component of the second heart sound on the phonocardiogram; A2–onset of flow, the Doppler isovolumic relaxation time measured as the interval between A2 and the onset of flow across the mitral valve; A velocity, peak velocity of the atrial component of mitral filling; E velocity, peak velocity of the early component of mitral filling; E/(E+A), ratio of peak early filling velocity to the sum of the peak early and the peak atrial filling velocities.
