Courtemanche model
WebAug 7, 2024 · Cellular electrophysiology was represented by the Courtemanche model for human atrial cells, with the model parameters set for normal and remodelled cells. The effect of fibrosis was modelled with a smoothly varying diffusion coefficient, obtained from sampling a Gaussian random field with length scales of between 1.25 and 10.0mm. ...

WebJan 14, 2024 · In contrast, in the Courtemanche model, the inhibition of IKr and IKs significantly prolonged APD and vice versa. Additionally, a 50% reduction of Ito density abbreviated APD in the Courtemanche model, while the same perturbation prolonged APD in the Grandi model. Similarly, a strong model dependence was also observed at tissue … WebApr 9, 2007 · At a normal heart rate of 60 bpm, the action potential duration (APD) of the Courtemanche model is too long (>280 ms). This is mainly due to the maximum conductance of the inward rectifier K + current being too small (g K1 =0.09 nS/pF). 4 The small value of g K1 yields a high-input membrane resistance (≈174 MΩ).

Webin The ‘Invisible Hand’ and British Fiction, 1818–1860, eleanor Courtemanche argues that Adam Smith’s concept of the invisible hand, in underscoring a tension between the actions of individuals and a larger force that organizes those actions, provides a useful model for thinking about the structure of the nineteenth-century British novel.
WebAug 29, 2024 · To demonstrate the utility of parameter SKIP, we used the Courtemanche model to simulate the electrical activity in the human atrium on a square, two-dimensional plane with 800 × 800 nodes. Over this plane, a grid of 39 × 39 virtual unipoles was created.
