  • Patent number: 11672460
    Abstract: A map of cardiac activation wavefronts can be created from a plurality of mesh nodes, each of which is assigned a conduction velocity vector. Directed edges are defined to interconnect the mesh nodes, and weights are assigned to the directed edges, thereby creating a weighted directed conduction velocity graph. A user can select one or more points within the weighted directed conduction velocity graph (which do not necessarily correspond to nodes), and one or more cardiac activation wavefronts passing through these points can be identified using the weighted directed conduction velocity graph. The cardiac activation wavefronts can then be displayed on a graphical representation of the cardiac geometry.

  • Publication number: 20220183610
    Abstract: Electrophysiological activity can be mapped using sub-intervals of electrophysiological signals. An electroanatomical mapping system receives a plurality of electrophysiological signals (402), each of which spans an activation interval. For each signal, the system identifies an initial event time within the activation interval, such as by identifying a time of maximum signal energy (404), and defines a sub-interval about the initial event time (406). The system then analyzes the sub-interval to identify one or more electrophysiological characteristics of the electrophysiological signal (408) and adds a corresponding electrophysiology data point to an electrophysiology map (410). Advantageously, the sub-interval can extend outside of the activation interval, such that the instant teachings allow for capture and analysis of deflections that occur at or near the boundaries of the activation interval.

  • Publication number: 20220160284
    Abstract: Electrophysiological signals from a graphical representation of an electrophysiology map including a plurality of electrophysiology data points can be sorted by receiving user inputs specifying a number of virtual electrodes for a virtual catheter and defining a pathway of the virtual catheter. A corresponding number of virtual electrodes can be defined on the pathway of the virtual catheter, and one or more electrophysiology data points relevant to electrical activity at the virtual electrodes can be identified, allowing output of a graphical representation of electrophysiological signals corresponding to the identified electrophysiology data points. Relevant electrophysiology data points can be identified by applying one or more relevance criterion, such as a distance criterion, a bipole orientation criterion, a time criterion, and/or a morphology criterion.

  • Patent number: 10441187
    Abstract: An efficient system for diagnosing arrhythmias and directing catheter therapies may allow for measuring, classifying, analyzing, and mapping spatial electrophysiological (EP) patterns within a body. The efficient system may further guide arrhythmia therapy and update maps as treatment is delivered.
