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.

System and method for cardiac mapping

When generating anatomical maps (e.g., anatomical geometries and/or electrophysiology maps), it can be desirable to analyze whether or not a collected data point was collected from a region of interest. During an electrophysiology study, for example, an electroanatomical mapping system collects electrophysiology data points, each including an electrogram signal. By defining both a window of interest and a window of exclusion within the electrogram signal, the electroanatomical mapping system can analyze collected data points to determine whether or not they should be included in a map. In particular, the electroanatomical mapping system can compare the electrophysiology signal within the window of interest and the window of exclusion with respect to at least one signal parameter and add the data point to the map if the comparison satisfies at least one corresponding inclusion criterion. Applicable signal parameters include maximum peak-to-peak voltage, conduction velocity, and electrogram morphology.
