Fig. 2From: A new myofilament contraction model with ATP consumption for ventricular cell modelThe [Ca2+]–F b (a, c) and [Ca2+]–v ATPase (b, d) relations measured at different half sarcomere lengths (halfSL) of 0.8, 0.9, 1.0, and 1.1 µm, illustrated as gradations in color from gray to black, respectively. a [Ca2+]–F b relation, b [Ca2+]–v ATPase relation, c, d the x-axis and y-axis are indicated by Eq. 16. The halfSL was fixed at 1.1 µmBack to article page
