Example of Incorrect Automatic Annotation (A) The electrogram corresponding to the blue point (red arrow) is automatically annotated on the far field ventricular signal (V), because this signal is larger than the near field atrial signal (A). Note that blanking of the V (red column) was set to avoid this error; however, it was too narrow to cover the late V electrograms that appear close to the tricuspid annulus. The area of incorrect annotation (inside black box) on the RA map is easily recognized as a spot of inconsistent color coding. (Right) Manual correction of the annotation is shown. This results in a change of the color and shape of the point on the map that now appears as an orange ring. (B) Area of incorrect annotation (inside black box, magnified in the middle) is shown as a spot of inconsistent color coding on the left ventricular map during ventricular tachycardia because of an artifact that was mistaken for the QRS complex (V). RA = right atrium.
