Box 4 Outlines the calculation used to calculate regurgitant fraction (RF).
\({\mathbf{RF}} = {\mathbf{RVol}}/{\mathbf{SV}} \times {\mathbf{100}}\) |
where RVol = regurgitant volume, SV = stroke volume. |
\({\mathbf{RF}} = {\mathbf{RVol}}/{\mathbf{SV}} \times {\mathbf{100}}\) |
where RVol = regurgitant volume, SV = stroke volume. |
