| Description
| - We report here the first quantitative evaluation of the role of the transverse-axial tubular (TAT) system in the electrical activity of cardiac cells. Our approach uses a biophysically-based representation of the TAT-system incorporated into a model of cardiac ventricular cell (Jafri et al., Biophys. J. 1998, 74:1149-68). The model was modified to agree more closely with recent published data. The differential distribution of ion transfer mechanisms in peripheral and tubular membranes was included (e.g. K+ channels; Christé, J. Mol. Cell. Cardiol. 1999, 31:2207-13). Changes of ion concentrations in the TAT-lumen were computed from the total transmembrane ion fluxes and ion exchanges with the pericellular medium. Long term stability of the model was verified at rest and under regular stimulation, the charge conservation principle being respected. The tubular membrane voltage during an action potential was nearly identical with the peripheral membrane voltage, indicating that propagation of excitation a
