MODEL STATUS : This model conforms to the CellML 1.0 Specification released on
10th August 2001, and the CellML Metadata 1.0 Specification released on 16th
January, 2002.
DESCRIPTION : This file contains a CellML description of Hunter, McCulloch and ter Keurs's 1998 mathematical model of the mechanical properties of cardiac muscle.
CHANGES:
16/04/2002 - CML - Corrected the name of the model, from HMK to HMT. Merged
the two equations for T_11 into one, piecewise equation.
18/07/2002 - CML - Added more metadata.
20/08/2002 - AAC - Removed the 'passive_elasticity' component.

<para>
Finite element models of the electrical and mechanical behaviour of the whole heart are well established. At the cellular level, there are several models published which describe the changes in ion concentrations and membrane ionic currents underlying the cardiac cell action potential. However, the Hunter-McCulloch-ter Keurs 1998 model is the first to capture the mechanical properties of actively contracting cardiac muscle. The model is based on an extensive review of experimental data from a variety of preparations and species. These experiments are interpreted with a four state variable model which includes i) the passive elasticity of myocardial tissue, ii) the rapid binding of Ca<superscript>2+</superscript> to troponin C, iii) the kinetics of tropomyosin movement and iv) the kinetics of crossbridge tension development.

This is the CellML description of the Hunter-McCulloch-ter Keurs
mathematical model of the mechanical properties of passive and active
cardiac muscle. It is unique in that it combines electrical and
structural data from the whole heart and transmembrane ionic fluxes at the cellular level.
