Claim Text:
1. A method, comprising: measuring electrical activity at multiple points on a surface of a heart of a patient using one or more sensors attached to a body of the patient positioned near the heart for receiving electro-cardiac signals from the heart; percutaneously inserting a catheter into a chamber of the heart and measuring local electrical activity at multiple points on the surface of the heart with the catheter; tracking a position of the catheter in the heart at each of the multiple points on the surface of the heart and recording the local electrical activity at each of the multiple points on the surface of the heart using a mapping and navigation system operatively connected to the catheter; receiving heart image data as well as the measured local electrical activity and the position of the catheter recorded at each of the multiple points on the surface of the heart and user input indicative of a spectral slice selected from a frequency band of the electro-cardiac signals from the heart by the one or more sensors attached to the body of the patient; calculating respective levels of the electrical activity within the selected spectral slice; and displaying the calculated levels of the electrical activity within the selected spectral slice on a 3-D map of the heart on a display.
