First Claim
Patent Images
1. A method of processing cardiac activation information associated with a complex heart rhythm disorder, the method comprising:
- obtaining cardiac information signals from sensors associated with a patient;
accessing, via a computing device, the cardiac information signals from the sensors associated with a plurality of locations of a patient'"'"'s heart, the signals including at least a first signal and a second signal; and
determining, via a computing device, activations in the cardiac information signals, wherein at least one activation associated with a beat in the first signal from the sensors at a first location is determined at least with reference to an activation associated with a beat in the second signal at a second location, the first location and second location being proximate neighbors.

Abstract
System, assembly and method are provided to facilitate reconstruction of cardiac information representing a complex rhythm disorder associated with a patient'"'"'s heart to indicate a source of the heart rhythm disorder. The complex rhythm disorder can be treated by application of energy to modify the source of the rhythm disorder.

48. A method of processing cardiac activation information associated with a heart rhythm disorder, the method comprising:
-
obtaining cardiac information signals from sensors associated with a patient; accessing, via a computing device, the cardiac information signals from the sensors associated with a plurality of locations of a patient'"'"'s heart, the signals including at least a first signal and a second signal; defining, via a computing device, a time interval in the first signal, indicating how early a beat is able to activate and how late a beat is able to terminate based on at least one predetermined property; determining, via a computing device, activations in the first cardiac signal, wherein at least one activation associated with a beat in the first signal from the sensors at a first location is determined within the time interval, at least in reference to an activation associated with a beat in the second signal at a second location, the first location and second location being proximate neighbors; and constructing, via a computing device, a clinical representation associated with the complex rhythm disorder using the activations as determined.
