Abstract
An example method of representing cardiac information associated with a heart rhythm disorder is disclosed. The method includes accessing a plurality of neighboring cardiac signals obtained from a patient. The method also includes eliminating far-field activations from the plurality of neighboring cardiac signals using one or more divergence criteria that define local activations in the plurality of neighboring cardiac signals, the divergence criteria being associated with divergence among the plurality of neighboring cardiac signals. The method further includes constructing a clinical representation of local activations in the plurality of neighboring cardiac signals.
Claims22
A method of representing cardiac information associated with a heart rhythm disorder, the method comprising:
- accessing a plurality of neighboring cardiac signals obtained from a patient;
- eliminating far-field activations from the plurality of neighboring cardiac signals using one or more divergence criteria that define local activations in the plurality of neighboring cardiac signals, the divergence criteria being associated with divergence among the plurality of neighboring cardiac signals;
- and
- constructing a clinical representation of the local activations in the plurality of neighboring cardiac signals.
