    Abstract: This invention is systems and methods to examine heart tissue morphology using a pair of electrodes (38), at least one of which is located in contact with heart tissue (12). The systems and methods transmit electrical current in a path through the contacted heart tissue (12) between the pair of the electrodes to derive a tissue electrical characteristic based, at least in part, upon sensing the impedance of the tissue lying in the path. The system and methods also sense with at least one of the electrodes the timing of local depolarization events in the contacted heart tissue. The systems and methods make possible the use of multiple endocardial electrodes (30) for taking multiple measurements of the electrical characteristics of heart tissue. Multiplexing can be used to facilitate data processing. The systems and methods also make possible the identification of regions of low relative electrical characteristics, indicative of infarcted tissue, without invasive surgical techniques.

    Abstract: This invention is systems and methods to examine heart tissue morphology using three or more spaced electrodes (38), at least two of which are located within the heart in contact with endocardial tissue. The systems and methods transmit electrical current through a region of heart tissue lying between selected pairs of electrodes (224), at least one of the electrodes in each pair being located within the heart. The systems and methods derive the electrical characteristic of tissue between the electrode pairs (206) based, at least in part, upon sensing tissue impedances.

    Abstract: An electrode support for use in an intraventricular cardiac diagnosis and treatment includes at least one elongated spline (76) that carries at least one electrode (22). The spline has a rectangular cross section. It has a substantially greater width than thickness. The spline can be flexed in one vertical plane that passes through its longitudinal axis. The spline resists twisting and resists flexing in all other planes passing through the axis.
