Abstract: Disclosed is an electrode strip (100) for use in electrocardiography comprising a flexible and substantially inextendible substrate (104), a plurality of conductors (114) that extend along the substrate to form a plurality of electrode sites (V.sub.1 -V.sub.6, RA, LA, LL, RL), and a cover layer(122) that insulates the conductors. A plurality of regions of extensibility (102) in the strip allow selective positioning of the electrode sites on a body.

Abstract: Disclosed is a combined skin preparation and monitoring electrode (12). The electrode reduces motion artifacts in recording biopotentials by penetrating a patient's skin prior to acquiring biopotentials. Penetration of the skin reduces skin impedance and the skin's propensity to generate motion artifacts. The electrode has a resilient dome (16) with penetration tines (18) extending from the concave inner surface of the dome. Upon application of a force to the dome, the dome moves from a first position to a second position, forcing the penetration tines into a patient's skin. Upon removal of the force, the dome moves back to its original configuration, withdrawing the penetration tines from the patient's skin.

Abstract: Disclosed is an electrode strip (10) for use in electrocardiography comprising a flexible and substantially inextendible substrate (14), a plurality of conductive leads (16) and an insulating cover layer (17) including a plurality of apertures (24) therethrough. The conductive leads extend from a connector (22) to different ones of the apertures to form electrode sites (26). A plurality of regions of extensibility (30) in the strip allow selective positioning of the apertures on a body.
