Claim:
1. A method for catheter guidance in a heart, comprising: introducing a spiral mapping catheter into a patient, said mapping catheter further comprising a coiled distal end and a plurality of electrodes are arranged along said coiled distal end to form a conductive ring; moving said mapping catheter within the patient to bring one or more of said plurality of electrodes of said mapping catheter in contact with tissues in the heart at various locations to generate a desired map; identifying a target location from said map and placing one or more of said plurality of electrodes of said mapping catheter proximate to said target location; displaying at least one electrogram trace for said one or more of said plurality of electrodes; receiving an input that selects said target location with a cursor placed on said at least one electrogram trace for said one or more plurality of electrodes; synchronizing live electrode positions of the catheter tip and live electrode positions of the spiral catheter electrode; automatically guiding an ablation catheter to the one or more of said plurality of electrodes of said mapping catheter proximate to said target location in response to the received said input; and acquiring tissue contact between the tip of said ablation catheter and said target location by moving the tip of said ablation catheter past the one or more of said plurality of electrodes of said mapping catheter proximate to said target location.
