摘要
A system includes signal acquisition circuitry and a processor. 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 processor is configured to perform a sequence of annotation-visualization operations at subsequent times, by performing, in each operation: extracting multiple annotation values from the intra-cardiac signals, selecting a group of the intra-cardiac signals, identifying in the group one or more annotation values that are statistically deviant by more than a predefined measure of deviation, and visualizing the annotation values to a user, while omitting and refraining from visualizing the statistically deviant annotation values. The processor is further configured to assess, over one or more of the annotation-visualization operations, a rate of omissions of annotation values, and to take a corrective action in response to detecting that the rate of omissions exceeds a predefined threshold.
