Abstract
- Pacing and sensing are two different functions which can be accomplished by one and the same electrode. Optimal pacing requires a high tissue resistance in order to minimize the stimulation energy, making a small surface electrode highly desirable. For adequate sensing, however, the tissue resistance should be as low as possible which requires a larger electrode surface area. Decreasing the electrode surface area results in an increased polarization impedance. As this latter should be low for both pacing and sensing, an electrode with a large surface area should be used. How can these opposing needs be met by one electrode? The combination of a small geometrical surface and a large porous microstructure along with the choice of low polarizable materials meets both the requirements of pacing and sensing.
