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
