Abstract: An electrode system for use in administering an EKG test, provided as a chair with a flexible strap having electrodes embedded therein. The flexible strap is attached to the chair back rest and is tightened around the chest when the patient is seated in the chair. Electrodes fitted in the lower portion of the chair and the armrest make connection, respectively, to the legs and arms, thereby completing the test set-up procedure in a short time period. The electrodes embedded in the flexible strap are adjustable horizontally, and the strap itself is adjustable vertically, so that particular locations on the chest are reachable, making the strap suitable for all size patients. The chair is designed to become a bed to increase patient comfort. A set of exercise accessories is removably attachable to the chair, to permit EKG measurements during physical exertion.
