    摘要： A leadless pacemaker (102, 104) comprises a memory (156) storing first and second versions of a morphology template (604) corresponding to far-field signal components expected to be present in an EGM sensed by the LP (102, 104) when the patient has a first or second posture and a pacing pulse delivered to a remote cardiac chamber by a further LP (104, 102). The LP (102, 104) compares a morphology of a portion of the sensed EGM to a selected version of the morphology template (604) to determine whether a match therebetween is detected. Additionally, the LP (102, 104) determines whether capture occurred or failed to occur, based on whether the LP (102, 104) detects a match between the morphology of a portion of the sensed EGM and the selected versions of the morphology template (604).

    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.
