The majority of patients with abnormal flow patterns and pulmonary hypertension had increased RA v wave pressure, implying that the Df velocity was increased (exaggerated y descent). The increased v wave pressure was shown to be a result of an increased RV early diastolic and pre-a wave pressure. The incidence of congestive heart failure was higher in patients with Sf < Df and Df alone compared to the pattern of Sf = Df. This indicated that decreased RV systolic function (decreased x' descent) also played a part. This seems to be a later phenomenon in serial observations (41) (Fig. 18).
