摘要： An example method includes performing amplitude-based detection to determine location of R-peaks for a plurality of electrograms. The method also includes performing wavelet-based detection to determine location of R-peaks for the plurality of electrograms. The method also includes adjusting the location of the R-peaks determined by the wavelet-based detection of R-peaks based on the location of R-peaks determined by the amplitude-based detection of R-peaks. The method also includes storing, in memory, R-peak location data to specify R-peak locations for the plurality of electrograms based on the adjusting.

摘要： An example method includes storing invasive position data representing different positions of one or more sensors in a given coordinate system within a volume defined by an electromagnetic field and storing non-invasive position data representing different positions of a plurality of control points in the given coordinate system determined from a position of one or more sensors. The method also includes computing internal geometry data based on the invasive position data, the internal geometry data representing a three-dimensional anatomical surface within a patient's body. The method also includes computing electrode geometry data based on the non-invasive position data, the electrode geometry data representing a location of each of a plurality of electrodes on an outer surface of the patient's body. Electrical activity sensed by the plurality of electrodes can be reconstructed onto an anatomical envelope within the patient's body.

摘要： An electrical connector has dielectric posts surrounding the contacts and extending outwardly from the root along the contact axis a finite amount. The mating connector (or plug) has a housing that surrounds the posts. A device that includes both the electrical connector and the mating connector provides good electrical isolation between adjacent contacts.

摘要： A method can include storing a plurality of data sets including values computed for each of a plurality of points for a given spatial region of tissue, the values in each of the data sets characterizing electrical information for each respective point of the plurality of points for a different time interval. The method can also include combining the values computed for each of a plurality of points in a first interval, corresponding to a first map, with the values for computed for each of the respective plurality of points in another interval and to normalize the combined values relative to a common scale. The method can also include generating a composite map for the given spatial region based on the combined values that are normalized.

摘要： A method can include storing input electrical signal data representing at least a given electrophysiological signal acquired from a patient. A non-local mean filter can be applied to the given electrophysiological signal, the non-local mean filter including a spatial filter component and an intensity filter component.

摘要： A computer-implemented method can include determining an amplitude for each of a plurality of input channels, corresponding to respective nodes. A measure of similarity can be computed between the input channel of each node and the input channel of its neighboring nodes. The method can also include comparing an amplitude for each node relative to other nodes to determine temporary bad channels. For each of the temporary bad channels, a measure of similarity can be computed between the input channel of each node and the input channel of its neighboring nodes. Channel integrity can then be identified based on the computed measures of similarity.

摘要： A method to calculate and visualize dynamic wave front propagation of electrical signals on a geometric surface is described. Wave front locations are identified on the geometric surface between each identified pair of adjacent nodes on the geometric surface. A graphical map can be generated to represent the identified wave front locations on at least a portion of the geometric surface.

摘要： A circuit board connector is disclosed that has isolator ribs between contact tails, and slots in the edge of a circuit board between circuit pads that communicate with the ribs to avoid pad-to-pad current leakage and high-voltage breakdown. The slots may be between individual circuit board fingers that each include one of the conductor pads.
