Abstract: Methods and systems for cardiac mapping are disclosed. An example system includes a catheter shaft with one or more electrodes coupled to a distal end of the catheter shaft. Electrodes sense electrical signals at anatomical locations within a heart. A processor coupled to the catheter shaft acquires electrogram signals of the heart using the electrodes. Each electrogram signal relates to three-dimensional positional data corresponding to the anatomical locations. The processor also store the electrogram signals of the heart corresponding to electrical activities sensed at corresponding anatomical locations, calculate an activation recovery interval associated with each of the corresponding anatomical locations, determine spatial gradient data of the activation recovery interval based on a distance between at least two neighboring anatomical locations. The system also includes a display device to display a three-dimensional graphical representation of the spatial gradient data between the at least two neighboring anatomical.

Abstract: A medical system for removing far-field signals from a unipolar electrical signal is disclosed. In embodiments, the medical system comprises a catheter and a processing device communicatively coupled to the catheter. The catheter comprises a plurality of electrodes configured to sense a plurality of unipolar signals transmitted through tissue. The processing device is configured to: receive the sensed unipolar electrical signals, determine an electrode having a high level of contact with the tissue, and determine an electrode having a lower level of contact with the tissue than the electrode having the high level of contact with the tissue. Further, the processing device is configured to determine a sensed near-field electrical signal based on the unipolar electrical signal received from the electrode having the high level of contact and the unipolar electrical signal received from the electrode having the lower level of contact.
