System and method for reconstructing cardiac signals associated with a complex rhythm disorder |
摘要 |
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. |

1. A system to reconstruct cardiac signals associated with a complex rhythm disorder received from a plurality of sensors associated spatially with a patient's heart, the system comprising at least one computing device that comprises:
an analytic engine comprising:
a beat classification module configured to identify a plurality of discernible beats on high-confidence signals of sensors that are spatially adjacent to a sensor associated with a low-confidence signal, the discernible beats on the high-confidence signals corresponding to a non-discernible beat on the low-confidence signal;an activation onset module configured to:compute a time vector between at least two activation onsets associated with the identified discernible beats on the high-confidence signals through the non-discernible beat on the low-confidence signal;define a time interval associated with the non-discernible beat about a region of the low-confidence signal where the computed time vector crosses the non-discernible beat, the time interval indicating how early the non-discernible beat is able to activate based on a previous beat on the low-confidence signal that has a selected or determined activation onset and how late the non-discernible beat is able to terminate based on at least one predetermined property; andassign the non-discernible beat an activation onset during the defined time interval that is closest to the computed time vector; and a representation tool configured to generate a clinical representation associated with the complex rhythm disorder using at least the activation onset assigned to the non-discernible beat. |
