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.
Claims90
A method of processing cardiac activation information associated with a heart rhythm disorder, the method comprising:
- accessing cardiac information signals 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 activations in the cardiac information signals, wherein at least one activation associated with a beat in the first signal at a first location is determined 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.
A method of processing cardiac activation information associated with a heart rhythm disorder, the method comprising:
- accessing cardiac information signals associated with a plurality of locations of a patient's heart, the signals including at least a first signal and a second signal;
- defining 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 activations in the first cardiac signal, wherein at least one activation associated with a beat in the first signal 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 s;
- and
- constructing a clinical representation associated with the complex rhythm disorder using the activations as determined.
A method of identifying a source of a heart rhythm disorder, the method comprising:
- accessing cardiac information signals 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 activations in the cardiac information signals, wherein at least one activation associated with a beat in the first signal at a first location is determined at least in reference to activations associated with beats in signals at second locations, the first location and second locations being neighbors.
