MULTIPLE CATHETER CARDIAC ELECTROPHYSIOLOGY SYSTEM

摘要

The invention relates to a modular control unit for a multiple catheter cardiac electrophysiology (EP) system. The modular control unit comprises a common interface configured for communicating with a computer through a computer interface port, a first catheter control module configured for cardiac EP-diagnosis, and a second catheter control module configured for cardiac EP-diagnosis. The first and second catheter control modules each have circuitry comprising a catheter port configured for electrically connecting one or more electrodes of an EP-catheter to the circuitry, an EP-signal recorder comprising devices for amplifying and processing EP-signals received from the catheter port, a stimulation section for feeding a cardiac stimulation signal to the catheter port, and a module-microcontroller (MCU) configured for controlling the operation of the EP-signal recorder and the operation of the stimulation section. The first and second catheter control modules are galvanically isolated from each other and communicate with the common interface through a respective, galvanically isolated module interface port.
