ABSTRACT:
A smooth surfaced, inelastic, flexible, belt-like strip for recording electrocardiograms having a series of six separate precordial electrodes, three fixed and three being independently movable leads with electrodes and movable within a fixed range insuring proper placement on the patient's chest or precordium during usage, the S-shape of the belt-like strip enables it to cover the proper recording areas. The fixed, electrodes, which are raised and compressible, maintain contact with patients' chests despite variations in chest size among patients. The apparatus is attached around the chest with an adjustable elastic strap providing a constant and evenly distributed downward force holding it and the precordial contacts, which are between the strip and patient's chest, in place. Internal lead wires attach at the sides of the precordial belt-like strip with electrodes placed on each arm via external lead wires. The internal lead wires from the precordial electrodes and from the left and right arm electrodes are inside or on the outside surface of the belt-like strip and emerge therefrom at one place to form a main cable which connects to an electrocardiograph machine. Two additional wire leads from electrodes on each leg enter the main cable to transmit signals from each lower limb electrode to the electrocardiograph machine. This device is reusable for many patients, easily cleaned and designed for use with a variety of body habitus.
