Abstract
Systems for examining heart tissue morphology deploy one or more electrodes into the heart in contact with endocardial tissue. The systems transmit electrical current from the electrodes in paths through the contacted endocardial tissue. Based upon these current transmissions, the systems derive the electrical characteristics of tissue lying in the path. This electrical characteristic can be directly correlated to tissue morphology. The systems maximize surface contact with endocardial tissue, while minimizing contact with the surrounding blood pool, to obtain accurate tissue electrical characteristic measurements.
