Abstract:
1. A method for sensing multiple local electric voltages from endocardial surface of a heart, comprising: providing a system for sensing multiple local electric voltages from endocardial surface of a heart, comprising: delivering the system to the heart; sliding the basket assembly beyond the distal end of the second elongate tubular member, whereby the splines radially expand into the radially expanded non-spherical shape to dispose the basket assembly within a chamber of the heart; contacting proximal heart tissue within the chamber of the heart with the substantially all of exposed electrodes disposed on the proximal spline portions; detecting multiple local electric voltages with the exposed electrodes contacting the proximal heart tissue from endocardial surface thereat; contacting other heart tissue within the chamber of the heart with substantially all of the exposed electrodes disposed on the medial spline portions and the distal spline portions; and detecting multiple local electric voltages with the exposed electrodes disposed on the medial spline portions and the distal spline portions contacting the other heart tissue from endocardial surface thereat.
