    摘要: A method, including receiving sets of signals during multiple cardiac cycles, each set indicating, for a probe inserted into a cardiac chamber, a 3D location of a distal end of the probe, electrical potentials measured at the location, and respective times during a given cycle when the potentials were measured. The received measurements and the respective times are compared to a first template for a sinus rhythm cycle and a second template for a non-sinus rhythm cycle so as to identify a sequence of cycles including consecutive first, second, and third cycles wherein the first and second cycles match the first template and the third cycle matches the second template. A physical map is generated based on the locations. Based on the received locations and corresponding potentials, an electroanatomic map including the local activation times for the non-sinus rhythm cycle overlaid on the physical map is rendered to a display.

    摘要: Systems, devices, and techniques are disclosed for automatically generating CPM matrices. The system includes a processor configured to receive a plurality of historical, sparse CPM matrices and a plurality of historical, supplemented CPM matrices, wherein each sparse CPM matrix is associated with a respective supplemented CPM matrix; train a learning system based on the plurality of historical, sparse CPM matrices and the plurality of historical, supplemented CPM matrices, wherein the learning system is trained so as to generate a supplemented CPM matrix given a sparse CPM matrix; receive, by the trained learning system, a new, sparse CPM matrix; and generate, with the trained learning system, a new supplemented CPM matrix.
