A method of conducting a therapeutic ablation of cardiac tissue based upon local electrical signals in the tissue. The method includes navigating at least one electrophysiology catheter to a plurality of locations on the surface of the heart using a remote navigation system; sensing the electrical activity in the heart tissue at a plurality of the locations in the heart; and storing a value representative of the control variables of the remote navigation system at the location and a value representative of the electrical signal at the location; displaying a representation of at least some of the locations where the electrical activity was sensed on a display using graphic indicators of the timing of the sensed activity relative to the reference; determining the location at which the sensed electrical activity is earliest relative to a reference electrocardiogram signal; and automatically navigating an electrophysiology catheter to a position relative to selected location, and ablating tissue at the location with the electrophysiology catheter.
