Electrocardiograph bioelectric interface system and method of use

摘要

A bioelectric interface (3) provides three Einthoven triangle equivalent lead forming electrodes positioned on a subject's chest so as to provide a Wilson common terminal (WCT) voltage essentially equivalent to that provided by an Einthoven triangle formed using leads positioned conventionally on a subject's limbs. Wilson common terminal (WCT) forming resistors can be of fixed values or variable to allow adjustment of a produced Wilson common terminal (WCT) voltage. Additional precordial electrodes are also typically present. Electrodes can consist of single elements or groups of electrode elements, and are present in locational regions of the bioelectric interface (3) which allow a single size system to fit to patients with various sized bodies. The presence of an "undulated" outer periphery bounbary (UOPB) comprised of a plurality of curves facilitates conformation to a subject's body, and removal of the bioelectric interface (3), in use. <IMAGE>
