Abstract:
Cardiac catheterization is performed with a catheter having a basket-shaped assembly at its distal end. A plurality of spline electrodes are disposed on the splines of the assembly. The assembly is configurable in an expanded arrangement wherein the splines bow radially outwardly and in a collapsed arrangement, wherein the splines are arranged generally along the longitudinal axis of the catheter body. A far-field electrode is disposed in the interior of the assembly. An intracardiac electrogram and a far-field electrogram are obtained with at least one of the spline electrodes and the far-field electrode, respectively. The far-field component is removed from the intracardiac electrogram using the far-field electrogram.

Claim (Index 1):
A method, comprising the steps of:\n inserting a catheter into a heart of a subject, the catheter having an elongated catheter body, the catheter body having an interior, proximal end, a distal end and at least one lumen therethrough and having a basket-shaped assembly at the distal end of the catheter body, the basket-shaped assembly having a longitudinal axis, a proximal extremity and a distal extremity and comprising a plurality of splines connected at the proximal extremity and the distal extremity, the splines comprising a plurality of spline electrodes, the basket-shaped assembly configurable in an expanded arrangement wherein the splines bow radially outwardly and in a collapsed arrangement, wherein the splines are arranged generally along the longitudinal axis of the catheter body, the catheter having a far-field electrode disposed in the interior of the expanded basket-shaped assembly; expanding the basket-shaped assembly to contact at least one of the spline electrodes with a surface of the heart; thereafter receiving an intracardiac electrogram with the at least one of the spline electrodes and receiving a far-field electrogram with the far-field electrode, the intracardiac electrogram having a near-field component and a far-field component; and removing the far-field component from the intracardiac electrogram while retaining the near-field component by applying the far-field electrogram to the intracardiac electrogram to generate a modified intracardiac electrogram; reporting the modified intracardiac electrogram, wherein the far field electrode is disposed on a longitudinal axis of symmetry of the basket shaped assembly.
