Abstract
Apparatus for endocardiac therapy, including an elongate probe for insertion into the heart of a subject, the probe having distal and proximal ends. The probe includes an ablation device near the distal end of the probe for ablating heart tissue and at least two sensing electrodes, for sensing activation signals in the heart tissue adjacent to the ablation device. Signal analyzer circuitry receives and correlates the activation signals. Preferably, the probe includes a position sensor adjacent to the ablation device, which generates signals responsive to the position of the probe with respect to an external frame of reference.
