Abstract
This invention relates to the determination and/or representation of physiological information relating to a heart surface.
Claims30
A method for providing information about a patient's heart, the method comprising:
- measuring signals from one or more electrodes at multiple positions in the heart cavity in response to electrical activity in the patient's heart cavity over multiple heart beat cycles;
- generating, by a computer, annotation information for the measured signals by applying one or more operators to the measured signals to identify at least one of regions of the heart having double deflections, regions of the heart having multiple deflections, regions of the heart having fractionation, regions of the heart having double activation, and regions of the heart having no activation;
- generating, by the computer, an electroanatomical representation of the patient's heart that includes at least some of the annotation information;
- receiving from an operator a change to the annotation information for a specified measured signal;
- and
- modifying, by the computer, annotation information for one or more other neighboring additional measured signals based on the change.
3 more elements
A system for providing information about patient's heart, the system comprising:
- one or more electrodes for measuring signals at multiple positions in the heart cavity in response to electrical activity in the patient's heart cavity over multiple heart beat cycles;
- and
- an electronic processor coupled to the one or more electrodes, wherein the electronic processor is configured to:
- generate annotation information for the measured signals by applying one or more operators to the measured signals to identify at least one of regions of the heart having double deflections, regions of the heart having multiple deflections, regions of the heart having fractionation, regions of the heart having double activation, and regions of the heart having no activation;
- generate by the computer, an electroanatomical representation of the patient's heart that includes at least some of the annotation information;
- receive from an operator a change to the automatically generated annotation information for a specified measured signal;
- and
- modify annotation information for one or more other neighboring additional measured signals based on the change.
