    摘要: Electroanatomic mapping of the epicardium includes acquiring first and second electroanatomic data from first and second epicardial locations, acquiring a closed 3-dimensional image of the epicardium and modeling the image as a 3-dimensional triangular mesh. The first and second locations align with front-facing triangles and rear-facing triangles of the mesh. The second locations are projected from the rear-facing triangles onto the closest front-facing triangles. The first and second electroanatomic data are displayed on the front-facing triangles and the closest front-facing triangles, respectively.

    摘要: Methods, apparatuses, and systems for intra-cardiac pattern matching are disclosed. A unipolar pattern intra-cardiac (IC) electromyography (EGM) signals is received for an area of a heart from a plurality of activity channels corresponding to a plurality of electrodes of a catheter. A window of interest (WOI) of the IC EGM signals is received representing an entire cycle length for a single heartbeat. A pattern of interest (POI) is selected to include a portion of WOI corresponding to an arrhythmia activation. A template POI is generated representative of the arrhythmia activation. Subsequent electrical activity is received, weights are applied and the subsequent electrical activity is compared with the template POI. A correlation score is generated and compared with a threshold correlation score.

    摘要: Methods, apparatus, and systems for medical procedures are disclosed herein and include receiving a first electrical activity at a first time for a plurality of points on an intrabody surface. A first cluster of points is identified from the plurality of points, based on the first electrical activity, the first cluster of points each exhibiting electrical activity above an activity threshold. A second electrical activity is received at a second time for the plurality of points on the intra-body surface. A second cluster of points is identified from the plurality of points, based on the second electrical activity. The first cluster of points and the second cluster of points are determined to be related based on a propagation threshold. A first visual indication for a first propagation route is provided from the first cluster of points to the second cluster of points.

    摘要: Described embodiments include a method that includes constructing a computerized electroanatomical model of a portion of a heart, the model including a mesh, which approximates the portion of the heart, and a plurality of points, at different respective locations on the mesh, having respective associated local activation times (LATs) that were ascertained from electrocardiographic signals acquired from the portion. The method further includes constructing a graph that interconnects the points and, based on the respective locations and LATs of the points, identifying, from a plurality of pathways, through the graph, from a first one of the points having a lowest one of the LATs to a second one of the points having a highest one of the LATs, both a shortest pathway and a longest pathway. The method further includes displaying the mesh, with the identified shortest pathway and longest pathway superimposed over the mesh. Other embodiments are also described.
