| pubmed-article:1253191 | pubmed:abstractText | In this study the applicability of the phase-plane technique for interpreting membrane properties of cardiac cells in a two-dimensional structure is discussed. The conditions are derived for which the effects of two-dimensionality of a sheet can be neglected and for which the one-dimensional phase-plane technique for estimation of the membrane current densities remains valid. The usual phase-plane technique appears to be applicable to nodal and atrial tissue. | lld:pubmed |
