Systems and methods for performing electrophysiology (EP) signal processing

A system for performing electrophysiology (EP) signal processing, comprising:

• an electrocardiogram (ECG) circuit board configured to receive an ECG signal, wherein the ECG circuit board comprises a large-signal detection circuit and a differential signal amplification stage, wherein the differential signal amplification stage is configured to amplify the ECG signal to output an output ECG signal and the large-signal detection circuit is coupled to the differential signal amplification stage and configured to remove signal saturation from the output ECG signal based on a time constant, wherein the time constant specifies a length of time that the output ECG signal is at maximum amplitude;
• a plurality of intracardiac (IC) circuit boards, each configured to receive a corresponding IC signal;
• a communications interface coupled to a remote device;
• and
• a processor, coupled to the ECG circuit board, the plurality of IC circuit boards, and the communications interface, configured to:
• receive, via the communications interface, feedback from the remote device;
• and
• control, via the communication interface, the remote device based on the ECG signal, the IC signals, or the feedback from the remote device.
