From this, a number of grades of diastolic function can be determined: # Normal diastolic function <unk>  > A) # Impaired relaxation <unk> :A reversal i.e.,<unk>  is 2) Pseudonormalisation shows a transmitral profile that appears normal. However, with the use of pulmonary vein pulsed wave Doppler, it can be shown that the relaxation pattern is abnormal (systolic blunting, a decrease in the height of the S wave). In addition, performance of a Valsalva manoeuvre will result in unmasking of the pseudonormal state.
