1. A method for use in operating an electrode catheter, the method comprising the steps of:

  • providing a navigation system for monitoring a position of a first electrode of said electrode catheter during a medical procedure;

    establishing an electrode coupling assessment system for evaluating an electrode-to-patient coupling condition indicative of a level of electrical coupling between said first electrode of said electrode catheter and a tissue, said assessment system adapted to distinguish between multiple levels of said electrode coupling condition including at least levels of insufficient coupling for a procedure and sufficient coupling for said procedure;

    operating said electrode coupling assessment system in connection with the medical procedure to compare an electrical signal measured between said first electrode and a second electrode to predetermined baseline ranges associated with said multiple levels of electrode coupling to identify said level of said coupling condition; and

    providing an output via said navigation system indicating said identified level of said coupling condition.
