Abstract:
A smooth surfaced, inelastic, flexible, S-shaped or L-shaped belt-like strip for recording electrocardiograms having a series of separate precordial electrical contacts and laterally placed separate, independently movable precordial leads and electrodes movable laterally insuring proper placement on the patient's chest or precordium during usage. The S- and/or L-shape of the strip helps cover proper recording areas. Raised, fixed, compressible precordial electrodes maintain contact with each patient's chest allowing for variations in chest size among patients. The apparatus is attached to the chest with an adjustable elastic strap providing a constant and evenly distributed downward force holding it and the precordial leads in place. Lead wires exit the lateral sides of the precordial belt-like strip towards electrodes placed on each arm. Lead wires from the precordial electrodes and from each of the left and right arm electrodes travel inside or on the outside surface of the S-shaped and/or L-shaped belt-like strip and emerge to form a main cable which connects via a suitable adapter or plug to an electrocardiograph machine.
