Abstract
A technique has been devised to pace the heart, defibrillate the heart, or ventilate the lungs of a patient using extremely low electrical power. These techniques use an internal esophageal electrode as the basic common terminal with chest electrodes positioned to direct a particular current to a particular place depending on whether pacing, defibrillation or ventilation is to be accomplished. In accordance with the present invention a particular configuration of multiple ring electrodes has been devised to facilitate these techniques.
