Abstract

Various embodiments provide a cardiac mapping and model merging method including: generating a premature ventricular contraction (PVC) activation map of a heart based on a three-dimensional (3D) heart model and PVC electrocardiogram (ECG) data recording during PVC of the heart; generating a 3D internal surface model of the heart by triangulating point-by-point contact data collected during an electrophysiology (EP) procedure; merging the 3D activation map and the 3D internal surface model to form a PVC activation surface model; and pacing the heart at a first pacing location disposed in an area of earliest activation identified in PVC activation surface model.
