Model Status

This variant of the model was created by Penny Noble of Oxford University, and represents the parameters given for the endocardial cell variant in Ten Tusscher et al. 2004. This file is known to run in PCEnv and COR.

Model Structure

Cardiac arrhythmias and sudden cardiac death are amongst the most common causes of premature death in the devloped world. However despite their prevalance, they remain relatively poorly understood. Mathematical models, which capture the function of the beating human heart, play an important role in cardiac research. In part this is because practical experiments on human hearts are limited, and animal hearts may differ significantly in their anatomy and physiology relative to the human heart. In addition, cardiac arrhythmias are three dimensional phenomena, while experimental observations are mainly limited to surface recordings.

Existing mathematical models of human ventricular cells include:

However, these models have their limitations, such as the fact that several of the equations are based on animal data. The aim of the 2004 study by ten Tusscher et al., is to develop a new model for human ventricular cells that is based on recent experimetnal data and that is computationally efficient for large-scale spatial simulations. A schematic diagrma of the modl can be seen in the figure below.
