From: Grading diastolic function by echocardiography: hemodynamic validation of existing guidelines
Implementation of guideline recommendations for diastolic function grading modified from reference 2. Abbreviations: DT = deceleration time; A = duration of atrial wave on mitral inflow; Ar = duration of pulmonary vein flow A wave reversal; Av E/e’: ratio between peak early velocity of mitral inflow and the average of early septal and early lateral mitral annulus peak velocities; E/A: ratio between peak velocities of early and late (atrial) waves seen on of mitral inflow; Val Δ E/A = change with Valsalva of E/A ratio
