Abstract
A method of generating a map of a portion of a patient's anatomy using an electroanatomical mapping system includes separating an anatomical region (e.g., the heart) into an inclusion region (e.g., the left atrium) and an exclusion region (e.g., the left ventricle) by defining a boundary surface (e.g., along the mitral valve). A label electrode carried by a multi-electrode catheter can be defined and used to determine whether or not to add an electrophysiology data point collected using the multi-electrode catheter to the map. In particular, electrophysiology data points can be added to the map of the portion of the patient's anatomy when they are collected with the label electrode within the inclusion region. Positions of the label electrode can also be used to define the boundary surface. Alerts can also be provided when the label electrode crosses the boundary surface and enters the exclusion region.
