    Abstract: A medical device, comprising: a memory; and a processing module configured to retrieve electrogram (EGM) data for N cardiac cycles from the memory, wherein N is an integer greater than 1, categorize each of the N cardiac cycles into one of a plurality of categories based on a morphology of the N cardiac cycles, perform comparisons be¬ tween pairs of the N cardiac cycles, each of the comparisons between two cardiac cycles comprising: detecting a mismatch between the two cardiac cycles when the two cardiac cycles are in different categories; and detecting a match between the two cardiac cycles when the two cardiac cycles are in the same category, wherein the processing module is further configured to classify the rhythm of the N cardiac cycles based on a number of detected matches and detected mismatches.

    Abstract: Techniques for evaluating cardiac electrical dyssynchrony are described. In some examples, an activation time is determined for each of a plurality of torso-surface potential signals. The dispersion or sequence of these activation times may be analyzed or presented to provide variety of indications of the electrical dyssynchrony of the heart of the patient. In some examples, the locations of the electrodes of the set of electrodes, and thus the locations at which the torso-surface potential signals were sensed, may be projected on the surface of a model torso that includes a model heart. The inverse problem of electrocardiography may be solved to determine electrical activation times for regions of the model heart based on the torso-surface potential signals sensed from the patient.
