Figure 4From: Elasticity-based determination of isovolumetric phases in the human heartChanges in wave amplitude U ( t ) and LV cross-sectional areas α LV ( t ) in a patient with LV relaxation abnormalities. The isovolumetric tension time (τA) is in the range of values measured in healthy volunteers. In contrast, the time of isovolumetric elasticity relaxation (τB) was significantly increased in patients. Further explanations are given in the caption to Figure 4.
