Abstract
A method of mapping arrhythmic activity, such as premature ventricular contraction ('PVC') activity, using an electroanatomical mapping system includes defining at least two arrhythmia template signals. Electrophysiology data points, each including an electrophysiological signal, are collected. A morphological similarity between the electrophysiological signal and a first arrhythmia template signal is computed; if this exceeds a preset threshold, then the electrophysiology data point is added to a corresponding arrhythmia map. If it does not, a morphological similarity between the electrophysiological signal and a second arrhythmia template signal is computed. If this exceeds the preset threshold, then the electrophysiology data point is added to a corresponding arrhythmia map. If neither exceeds the preset threshold, then the electrophysiology data point can be used to establish an additional arrhythmia map by defining an additional arrhythmia template signal.
