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 inputing front - end amplifiers which deliver the electrical signals from the intracardiac leads .
