Abstract
Systems and methods for optimal selection of beats for a 3D mapping are disclosed. A method in accordance with the present disclosure may be performed on a processor and may comprise receiving a plurality of beats from a catheter. The catheter may be located at a target mapping site, such as a chamber of the heart. A plurality of dynamic filters may be applied to the plurality of collected beats. The optimal beats may be determined and integrated as a beat in the 3D mapping system. This method enables the selection of more beats for a more comprehensive 3D mapping, as well as the selection of more quality beats that are representative of the target anatomy.
Claims20
A method comprising:
- receiving a plurality of beats from a catheter at a target mapping site;
- applying one or more first filters to each beat of the plurality of beats to determine a first subset of the plurality of beats;
- calculating one or more features of each beat of the first subset of the plurality of beats;
- applying one or more second filters to each beat of the first subset of the plurality of beats to determine a second subset of the plurality of beats, wherein the one or more second filters are associated with the calculated features;
- selecting optimal beats from the second subset of the plurality of beats;
- and
- integrating the optimal beats into a 3D mapping.
A system comprising:
- a processor configured to:
- receive a plurality of beats from a catheter at a target mapping site;
- apply one or more first filters to each beat of the plurality of beats to determine a first subset of the plurality of beats;
- calculate one or more features of each beat of the first subset of the plurality of beats;
- apply one or more second filters to each beat of the first subset of the plurality of beats to determine a second subset of the plurality of beats, wherein the one or more second filters are associated with the calculated features;
- select optimal beats from the second subset of the plurality of beats;
- and
- integrate the optimal beats into a 3D mapping.
A tangible non-transitory computer-readable medium in which program instructions are stored, which, when read by a processor, cause the processor to:
- receive a plurality of beats from a catheter at a target mapping site;
- apply one or more first filters to each beat of the plurality of beats to determine a first subset of the plurality of beats;
- calculate one or more features of each beat of the first subset of the plurality of beats;
- apply one or more second filters to each beat of the first subset of the plurality of beats to determine a second subset of the plurality of beats, wherein the one or more second filters are associated with the calculated features;
- select optimal beats from the second subset of the plurality of beats;
- and
- integrate the optimal beats into a 3D mapping.
