Claim Text:
1. A method for performing an electrophysiological procedure on a mammalian patient having a heart, comprising: positioning the mammalian patient such that the heart is in a main magnetic field of an MRI scanner; introducing an MR-compatible catheter into the heart; acquiring a magnetic resonance image of the heart by applying static and gradient magnetic fields to the mammalian patient and sensing radio frequency (RF) emissions from precession of protons in the heart excited by the static and the gradient magnetic fields; using the magnetic resonance image to position said MR-compatible catheter in the heart while continuing to acquire additional magnetic resonance images of the heart, establishing a conductive connection between the catheter and the heart while the catheter is in the static and gradient magnetic fields, and monitoring electrical signals in the heart acquired through the conductive connection between the catheter and the heart.
