Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
115 words
A method of transcutaneously pacing a patient's heart using two electrodes connected to a source of electrical pacing stimuli, at least one of said electrodes comprising a first electrical terminal for making a connection to an external source of electrical current, a second electrical terminal for making a connection to an external source of electrical current, a first skin-contacting region electrically connected to said first terminal of the electrode, and a second skin-contacting region electrically insulated from said first region and spaced laterally from said first region and electrically connected to said second terminal of the electrode, wherein said electrodes are placed on a patient to direct said electrical pacing stimuli to the patient's heart.
