Abstract: An ablation generator may include an input port for receiving a monitoring signal respective of tissue of the patient and an output port for providing the monitoring signal another device. A filtering circuit may be disposed between the input port and the output port, the filtering circuit configured to present a high impedance at one or more frequencies at or near which a mapping and navigation system associated with the ablation generator transmits a signal. The filtering circuit may additionally or alternatively be provided in a monitoring system or another component in an electrophysiology system.

Abstract: A system and method for tracking catheter electrode locations with the body of a patient during an MRI scan sequence includes mitigation logic configured to identify one or more impedance measurements that were taken during potentially noise-inducing conditions (i.e., magnet gradients, RF pulses), and were thus subject to corruption by noise. The mitigation logic is configured to replace the potentially corrupt impedance measurements with previously-obtained impedance measurements taken from an immediately preceding acquisition cycle (e.g., from a previous time-slice).
