Multiple ECG electrode strip
First Claim
1. An apparatus for placing on a patient'"'"'s chest for making ECG measurements, comprising:
- a strip of nonconductive film having a connector terminal at one edge for connection to an ECG measuring device;
a plurality of leads formed in the film and extending from the connector terminal;
a first set of electrodes on the strip and spaced in an array for contact with skin of a patient of a first size range, each of the electrodes of the first set being electrically connected to a separate one of the leads;
a second set of electrodes on the strip and spaced in an array for contact with skin of a patient of a second size range, each of the electrodes of the second set being electrically connected to a separate one of the leads;
at least some of the electrodes in the first set being electrically connected to the same leads as corresponding ones of the electrodes in the second set and spaced from said corresponding ones for placement on patients of different sizes; and
a backing layer covering a back side of the strip and the electrodes, the backing layer being divided into separate peel-off zones, whereby a technician may selectively remove certain of the zones and retain other of the zones, to expose only the electrodes for a selected patient size range.

Abstract
A harness for placing on a patient'"'"'s chest allows ECG measurements to be quickly made. The harness includes a strip of nonconductive film having a connector terminal at one edge for connection to an ECG measuring devise. The strip has a number of electrodes formed on it, each having leads extending to the connector terminal. At least some of the electrodes are grouped into sets. Each of the sets has a pattern of electrodes spaced for placement on a patient of a different size. Each of the electrodes within the sets has a corresponding electrode in another of the sets with which it is in electrical common. A backing layer may be peeled-off to expose the electrodes. The backing layer has separate zones, one for each of the sets of electrodes.

10. A method for placing ECG sensors on a patient'"'"'s chest, comprising:
-
providing a strip of nonconductive film with a connector terminal at one edge, a plurality of leads formed in the film and extending from the connector terminal, and a plurality of electrodes secured to the strip and electrically connected to the leads, with some of the electrodes being in sets with different patterns for different patient sizes, each of the electrodes in each of the sets having a corresponding electrode in another of the sets with which it is electrically in common; providing a backing layer which covers the electrodes, the backing layer being divided into separate peel-off portions; connecting the terminal to an ECG monitor; and based on patient size, selectively removing portions of the backing layer to expose one of the sets of electrodes while retaining the backing layer over the other of the sets, and placing the strip on the patient.
