Figure 3From: In vivo assessment of arterial stiffness in the isoflurane anesthetized spontaneously hypertensive rat Representative pressure-volume loops recorded with the Millar pressure-volume catheter system in a young and old rat. Effective arterial elastance, Ea = (Pes/SV) for each pressure-volume loop series. Pes = end systolic pressure and SV = stroke volume.Back to article page
