<title>Model Status</title>
<para>
This variant of the model was created by Penny Noble of Oxford University, and represents the parameters given for the M-cell variant in Ten Tusscher et al. 2004. A stimulus protocol component has been added to the model to allow simulation of trains of action potentials. This file is known to run in OpenCell and COR. This model is also associated with a OpenCell session file.
</para>
<para> This model is valid CellML and has full unit consistency.

<title>Model Structure</title>
<para>
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.
</para>
<para>
Existing mathematical models of human ventricular cells include:

<listitem>
<para>
Priebe and Beuckelmann, Electrophysiological Model of the Human Ventricular Myocyte, 1998; and</para>
</listitem>
<listitem>
<para>
Bernus <emphasis>et al.</emphasis> A Computationally Efficient Electrophysiological Model of Human Ventricular Cells, 2002.</para>
</listitem>
</itemizedlist>
<para>
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 <emphasis>et al.</emphasis>, is to develop a new model for human ventricular cells that is based on recent experimental data and that is computationally efficient for large-scale spatial simulations. A schematic diagram of the model can be seen in the figure below.

<rdf:value>Penny's file was modified to allow it to run in PCEnv. This required rearrangement of some differential equations such that the differential was on the left hand side.

<rdf:value>A stimulus protocol component was added to the model to allow simulation of trains of action potentials. Values for the amplitude (-52 picoA per picoF) and duration (1 ms) of the stimulus were taken from the original single stimulus in the model. The period of 1000 ms is intended to reflect beat period of the human heart, on which this model is based.</rdf:value>

<rdf:value>This variant of the model was created by Penny Noble of Oxford University, and represents the parameters given for the M-cell variant in Ten Tusscher et al. 2004. A stimulus protocol component has been added to the model to allow simulation of trains of action potentials (JL, 18/06/07). This file is known to run in PCEnv and COR.</rdf:value>
