Abstract

A system for monitoring a cardiac patient comprising an unit having a pair of spaced electrodes mounted on a resilient base which also carries a transmitter connected to the electrodes, and a receiver-adapter for receiving the transmitted signal from the transmitter, said receiver-adapter being coupled to a conventional display device, such as an oscilloscope.

Claims

1. An electrode transmitter combination for monitoring the heartbeat of a cardiac patient comprising base means including first and second pad means, first and second surfaces on said first pad means, third and fourth surfaces on said second pad means, said first and second pad means being oriented with said second and third surfaces in contiguous relationship, spaced electrode means proximate said first surface for engagement with the chest of said patient, self-contained transmitter means positioned between said second and third surfaces, lead means coupling said transmitter means to said electrode means, and means for adhesively securing said base means to the chest of said patient.

2. An electrode-transmitter combination for monitoring a cardiac patient as set forth in claim 1 including means for spacing said electrodes from the surface of the chest of said patient while maintaining them exposed to said chest.

3. An electrode-transmitter combination for monitoring a cardiac patient as set forth in claim 2 wherein said transmitter means is spaced between said electrodes.

4. An electrode-transmitter combination as set forth in claim 3 wherein said means for adhesively securing said base means to the chest of said patient comprises pressure sensitive adhesive on said first surface.

5. An electrode-transmitter combination for monitoring a cardiac patient as set forth in claim 4 wherein said transmitter means includes a battery for providing a power source therefor, and means maintaining said battery effectively uncoupled from said transmitter means and for permitting coupling of said battery to said transmitter means from outside of said pad means.
