1. An interface module for an electrophysiology laboratory (EP lab) system configured for use with a magnetic resonance imaging (MRI) system, the EP lab system including a medical device and at least one subsystem, the at least one subsystem including a diagnostic subsystem or a therapeutic subsystem, the interface module comprising:
a housing;
a first port on an exterior of the housing, the first port configured to mate with a first connector of the medical device that is electrically coupled to a high-impedance pathway of the medical device;
a second port on the exterior of the housing, the second port configured to mate with a second connector of the medical device that is electrically coupled to a low-impedance pathway of the medical device;
a third port on the exterior of the housing, the third port configured to mate with a first connector of the at least one subsystem;
a fourth port on the exterior of the housing, the fourth port configured to mate with a second connector of the at least one subsystem;
a high-impedance channel located within the housing, the high-impedance channel comprising first wired circuitry extending between the first port and the third port within the housing, the first wired circuitry configured to attenuate magnetic resonance radio frequency pulses and gradient field pulses generated by the MRI system while still communicating first electrical signals between the medical device and the at least one subsystem; and
a low-impedance channel located within the housing and including a plurality of electrical pathways, each of the plurality of electrical pathways comprising second wired circuitry extending between the second port and the fourth port within the housing, the second wired circuitry configured to communicate second electrical signals between the medical device and the at least one subsystem.
