US Patent 10932863 Methods of cardiac mapping and directional guidance

Various embodiments provide a cardiac mapping method including: generating an activation map of a heart based on electrocardiogram (ECG) data of a heart and a three-dimensional (3D) heart model; performing an electrophysiology (EP) procedure to determine a first pacing location; pacing the heart at the first pacing location using an EP catheter; determining whether the pacing at the first pacing location generates a desired cardiac response; displaying guidance information related to a second pacing location on one or both of the activation map and the internal surface map, when the first pacing location is determined not to generate the desired cardiac response; moving the pacing catheter to the second pacing location, based on the guidance information; and pacing the heart at the second pacing location.
