    摘要： A computer implemented method and system for identifying one or more areas of the heart muscle responsible for supporting or initiating abnormal heart rhythms using electrogram data recorded from a plurality of electrodes obtained from a corresponding series of sensing locations on the heart over a recording time period; the method including the steps of: setting a pre-defined geodesic distance, dividing the recording time period into several analysis time periods, and pairing each sensing location with a plurality of other sensing locations from within the defined geodesic distance, thus forming a plurality of location pairings; for each of the analysis time periods, defining the relative timing of each activation signal for each location within each pairing, determining whether the relative timing of activation signals falls within plausible biological parameters, defining the leading signal of the pair for each electrogram activation within the respective analysis time period; and assigning a series of lead signal scores to each electrogram pairing acquired within each analysis time period based on the proportion of time within the respective analysis time period that each activation signal is leading within each pairing; repeating the analysis at the same location at least once whilst varying the analysis time period; combining each analysis time period for each signal location to provide a statistical measure of the proportion that each signal location tends to lead relative to other locations within the defined geodesic area; and relating lead signal scores from overlapping geodesic areas to provide relative combined lead signal scores; to provide an indication of the relative likelihood that each sensing location is generally preceding other areas and is therefore at or adjacent to a driver area of the abnormal heart rhythm.

    摘要： A simulation manikin (1) for central venous cannulation comprises a first tube (3) for simulating a vein, a simulated clavicle (4), a first member (2) to which the tube (3) and simulated clavicle (4) are removeably affixed to in a position which is anatomically correct with respect to each other and a second member (11) having a surface which simulates the contours of half a neck to the clavicle. The manikin (1) is useful for teaching students identification of key anatomic landmarks, navigation of needle under ultrasound, recognition of correct blood vessels, and avoiding and managing potential complications.
