Patent ID: 11497427

Abstract:
A system includes signal acquisition circuitry and a processing unit. The signal acquisition circuitry is configured to receive multiple intra-cardiac signals acquired by multiple electrodes of an intra-cardiac probe in a heart of a patient. The processing unit is configured to select a group of the intra-cardiac signals, extract a respective most-likely annotation value from each of the intra-cardiac signals in the group, in accordance with a likelihood criterion, identify in the group an intra-cardiac signal whose most-likely annotation value is statistically deviant in the group by more than a predefined measure of deviation, extract, from the intra-cardiac signal having the statistically deviant annotation value, at least a second-most-likely annotation value in accordance with the likelihood criterion, and, responsive to a statistical deviation of the second-most-likely annotation value, select a valid annotation value for the corresponding intra-cardiac signal.
