    摘要： A method includes receiving intracardiac electrogram (IEGM) signals measured at a plurality of locations in a region of a heart that contains a His bundle of the heart. The IEGM signals are processed to find respective local activation time (LAT) values. A cluster of the locations is identified at which peaks associated with the LAT values occur later than a defined time. Respective time differences are calculated between times of occurrence of the associated peaks and a reference time. The time differences are compared to a threshold value to retain locations for which the time differences are below the threshold value. The respective IEGM signals are filtered to identify respective high-frequency peaks in the IEGM signals. The high-frequency peaks are cross-corelated to identify a subset of the locations whose high-frequency peaks meet a predefined cross-correlation level. The high-frequency peaks are tagged as His peaks and indicated on a cardiac map.

    摘要： Apparatus, including an enclosure having a base and a cover with respective conductive layers. The conductive layers connect to form a shield attenuating electromagnetic radiation originating outside the enclosure in a range of 10 kHz-100 kHz by at least 20 dB within the enclosure. An adapter circuit within the enclosure processes electrophysiological signals to generate an output signal. A first connector passing through the enclosure connects to a probe to receive the electrophysiological signals and convey them to the adapter circuit. A second connector passing through the enclosure receives the output signal from the adapter circuit and conveys it to a console. A control input receives a control signal indicative of a frequency within the range, and a sensing circuit senses a magnetic field within the enclosure and outputs a warning signal when the magnetic field at the frequency indicated by the control signal exceeds a preset threshold.

    摘要： A medical system includes a catheter configured to be inserted into a body part of a living subject, and including a distal end comprising an electrode, and a processor configured to compute position coordinates of the electrode, and find a measure of proximity of the electrode to tissue of the body part responsively to the position coordinates of the electrode and position coordinates of a wall of an anatomical map of the body part.
