Table 3 Comparison of flow propagation velocity measurements by three methods

From: Flow propagation velocity is not a simple index of diastolic function in early filling. A comparative study of early diastolic strain rate and strain rate propagation, flow and flow propagation in normal and reduced diastolic function

  Front of aliased velocity Black-to-colour transition Main aliased velocity
Controls 54.8 (5.5) 55.5 (17.7) 72.1 (40.6)
Patients 69.9 (13.5) 144.1 (110.0) 137.2 (116.0)
P: < 0.002 < 0.02 0.08 (NS)
R: -0.57 (-0.79 – -0.23) -0.43 (-0.7 – -0.04) -0.19 (-0.54 – 0.22)
  1. P: significance of the differences between the two groups (Standard deviation in parentheses). R: Correlation with strain rate propagation velocity (95% confidence intervals in parentheses).
