Appendix C. Diastolic Function

a Average of septal and lateral velocities. TMF, transmitral flow; E, early filling peak velocity; A, late-filling peak velocity; DT, deceleration time of E wave; IVRT, isovolumic relaxation time; PV-S, peak velocity of systolic component; PV-D, peak velocity of diastolic component; PV-AR, peak velocity of atrial reversal flow; PV-ARdur, duration of atrial reversal flow; Adur, duration of A wave; PVF, pulmonary venous flow; E′, peak tissue velocity in early diastole; Vp, velocity of propagation.

Values are expressed as mean ± standard deviation. aFor the age group 21-60, values are expressed as range of means. A′, late lateral annulus tissue velocity; A, late transmitral velocity; Ar, pulmonary venous atrial reversal velocity; D, pulmonary venous diastolic velocity; DT, deceleration time; dur, duration; E′, early lateral annulus tissue velocity; E, early transmitral velocity; IVRT, isovolumic relaxation time; ms, milliseconds; S, pulmonary venous systolic velocity.
