| Summary: | The present invention generally relates to medical electrical stimulation, and more particularly, to a lead system for providing medical electrical stimulation to either two locations in a single atrium or to a site in each of the two atria of a patient's heart.
A system for providing medical electrical stimulation includes a pulse generator coupled to a lead having two electrodes for placement in the right atrium or for placement of one in the right atrium and one in the coronary sinus or coronary vein. In the preferred embodiment the surface area of the first electrode is smaller than that of the second electrode so that the sensed signal from the first electrode is less than that from the second. The system provides dual site pacing with essentially single site sensing without the use of extra switches, connectors, or adaptors. |
