Left ventricular diastolic filling can be determined reliably by Doppler-derived mitral and
pulmonary venous flow velocities. Diastolic filling abnormalities are broadly classified at
their extremes to impaired relaxation and restrictive physiology with many patterns in
between. An impaired relaxation pattern identifies patients with early stages of heart
disease, and appropriate therapy may avert progression and functional disability.
Pseudonormalization is a transitional phase between abnormal relaxation and restrictive …
