Abstract
A system, includes (i) a processor, which is configured to receive, in a zone between first and second regions of an organ of a patient, one or more signals, at least a signal among the signals includes first and second components indicative of an electrophysiological (EP) property of the organ, and based on a relation between the first and second components, the processor is configured to estimate a location of at least a transition zone between the first and second regions, and (ii) a display, configured to display at least the estimated transition zone over a map of the organ.
Claims20
A method comprising:
- estimating a transition zone between a first region and a second region of an organ based on analysis of electrophysiological (EP) signals obtained from tissue of the organ;
- generating a graphical representation of the organ;
- and
- rendering, on the graphical representation, a visual transition zone indicator corresponding to the estimated transition zone, the visual transition zone indicator being configured to visually distinguish the first region from the second region.
A method comprising:
- receiving, from at least one electrode in contact with tissue of a patient, an electrophysiological (EP) signal indicative of electrical activity of the tissue;
- determining, based on the EP signal, a plurality of features corresponding to EP activity sensed at different locations within the tissue;
- determining relationships among the plurality of features to identify a change in EP characteristics;
- and
- determining, based on the determined relationships, a location of a transition zone between a first tissue region and a second tissue region.
A method comprising:
- receiving electrophysiological (EP) signals from tissue of a heart via a catheter positioned within the heart;
- estimating, based on the EP signals, a location of a transition zone between a first cardiac region and a second cardiac region;
- presenting the estimated transition zone during a catheter-based cardiac procedure;
- determining a guidance of the catheter, wherein the guidance is associated with positioning or operation of the catheter relative to the estimated transition zone;
- and
- updating at least one of the estimated transition zone or the guidance of the catheter in response to additional EP signals received during the catheter-based cardiac procedure.
