Abstract
A signal management system is disclosed which integrates a patient switching box and an amplification unit into a single compact enclosure sufficiently small to reside by the patient table in an operating unit set up for electrophysiology procedures. The system includes a front panel designed to accept standard ECG leads, a plurality of intracardiac leads, including leads available for stimulation and/or lesion generation, and a plurality of pressure channels. The front panel also includes a touch screen display to allow quick assignments of labels to each of the ECG or intracardiac leads and the pressure channels. The system includes an onboard microprocessor which allows any operation performed on the System to be automatically updated on a remote computer processing unit if attached, and vice-versa. Digital signal processors are used in the system to perform switching operations on the electrical signals received, and to perform gain, limiting and/or filtering processes thereon. The digital signal processors are automatically calibrated to adjust for varying gain and phase performance of the inputting front-end amplifiers which deliver the electrical signals from the intracardiac leads.
