Abstract: A method for analyzing noise in an electronic signal monitoring study includes selecting a study signal for analysis, removing a study subject's physiological signal from the study signal, and performing a quantitative analysis on the study signal. A fingerprint of any noise present in the study signal is then created.

Abstract: A system in combination with a stimulator system and an electrophysiology recorder system in delivering a stimulator signal to a subject's heart is provided. The electrophysiology recorder system can be generally operable to acquire an electrocardiogram from the subject's heart. The system can include an electrical couple in electrical connection between the simulator system and the electrophysiology recorder. The electrical couple can be configured to communicate the stimulator signal without loading an impedance of the electrophysiology recorder system on the stimulator system.

Abstract: A system to use in combination with an ECG signal acquisition system connected to an arrangement of electrodes on a subject is provided. The system can include an antenna system in communication with the ECG signal acquisition system, a location tracking system operable to track a direction and a location of the antenna system relative to a reference, and an interface connected in communication with the ECG signal acquisition system and the location tracking system. The interface includes an output indicative of a direction of a source of the noise signal detected by the antenna system. A filter reduces an effect of the noise signal on an acquired ECG waveform data received by the ECG signal acquisition system.

Abstract: The digital signal amplifier and acquisition system includes at least one catheter input module (CIM) configured to receive, route and digitize incoming analog cardiac signals from a number of catheters, as well as outgoing stimulator pulses. A plurality of CIMs are mechanically stacked and electrically daisy-chained and coupled with a mounting. The mounting platter is clamped to the bedrail and provides a single digital output cable to the base. The system also includes an acquisition device and the aforementioned base, which is configured to collect, filter and distribute the acquired data. Lastly an analog output module receives filtered digital signals from the base and is configured to reconstruct analog representations of such filtered digital signals for outside devices.
