Haemodynamic characteristics of each stage
| HR (beats/min) | MAP (mm Hg) | SV (ml/beat) | ARV (ml/beat) | DPG (mm Hg) | ROA (cm2) | |
|---|---|---|---|---|---|---|
| Values are mean (SD). | ||||||
| *p<0.01, **p<0.05 v baseline. | ||||||
| ARV, aortic regurgitant volume; DPG, diastolic aortoventricular pressure gradient; HR, heart rate; MAP, mean aortic pressure; ROA, regurgitant orifice area; SV, stroke volume. | ||||||
