Abstract

An electrode combination for an end effector of a catheter may include a reference electrode and a sensing electrode positioned such that the reference electrode is recessed in relation to the sensing electrode so that the reference electrode is inhibited from contacting tissue while the sensing electrode is in contact with tissue. The reference electrode can function to detect far-field electromagnetic noise while the sensing electrode receives electrical signals from tissue and may also receive signals from far-field electromagnetic noise. Electrocardiograms of the electrical signals from tissue can be generated by subtracting, or otherwise compensating for, the far-field noise received by the sensing electrode based on the far-field electromagnetic noise received by the reference electrode. Preferably, the reference electrode and the sensing electrode have the same surface area as each other.
