1. An electrode for transcutaneously delivering defibrillation pulses to a patient'"'"'s heart, the electrode comprising:

  • an insulating substrate,a conducting plate having a top surface, a bottom surface, and an electrical terminal for making a connection to an external source of electrical current, said conducting plate being positioned with said bottom surface on said substrate, anda layer of electrolytic gel comprising a concentration of an electrolyte that produces a combination series resistance of two of said electrodes, when measured with the electrodes configured in a series circuit with a 50 Ω

    resistance, and with the electrolytic gel layer of each electrode in contact with that of the other electrode, that is greater than 1 Ω

    when a 200 Joule defibrillation pulse is discharged into the series circuit, said layer of electrolytic gel covering the entire top surface of said conducting plate, the gel contacting a patient'"'"'s skin when the electrode is positioned on the patient'"'"'s skin to thereby prevent said conducting plate from contacting the patient'"'"'s skin.
