A heart pacemaker including a two wave length reflectance oximeter for determining oxygen saturation. The pacing rate is increased or decreased in response to the measured oxygen saturation. By appropriate multiplexing and timing functions, the two wave length reflectance oximeter is included in a pacing lead coupled to the pacemaker which requires only three conductors.

Oxygen sensing pacemaker

An enclosure for electronics, particularly adapted for implantation in the human body. The enclosure is provided with at least one transparent wall allowing it to be used in applications requiring light emission or light detection such as reflectance oximeters. The mechanical elements of the enclosure are particularly adapted to facilitate the use of welding to provide a hermetic seal for the enclosure.
