ABSTRACT:
An indwelling multi-contact plunge electrode to measure the electrical output from areas of the myocardium on an individual, sequential or combination composite basis. The electrode comprises an outer flexible tube containing a plurality of wire leads having their distal ends projecting angularly through the wall of the tube adjacent the distal end thereof and their proximal ends connected to an electrical plug. The distal end portion of the electrode is stiffened and bent at a substantial angle to the proximal portion and the void in the lumen of the tube not occupied by the wire leads is filled with silicone rubber.
