Abstract
A system includes a catheter and a processor. The catheter includes a distal-end assembly coupled to a distal end of a shaft for insertion into a cavity of an organ of a patient, the distal-end assembly including (i) one or more functional electrodes configured to be placed in contact with wall tissue of the cavity and (ii) a reference electrode configured to be placed in the cavity but not in contact with the wall tissue. The processor is configured to (i) estimate one or more impedances between one or more of the functional electrodes and the reference electrode, and (ii) based on the impedances, determine, for at least a functional electrode from among the one or more functional electrodes, whether the functional electrode is in physical contact with the wall tissue.
