Abstract
A cardiac mapping and pacing system includes a cardiac catheter having multiple electrodes and further includes an electrophysiological biological recorder. An interface system coupled between the multiple electrodes and the biological recorder permits the biological recorder to receive, process and display data acquired from the electrodes even though the number of electrodes may exceed the number of available inputs to the biological recorder. An application specific integrated circuit (ASIC) implemented as a CMOS switching circuit matrix is used to effectively interface a number of individual electrodes with a variety of existing and custom biological recorders.
