Abstract

An electrode arrangement for low artifact electrocardiogram (ECG) monitoring and defibrillation, comprises at least one conductor print line body having a large silver conductor print line area functioning as a defibrillation area and a small silver-silver chloride (Ag/AgCl) conductor print line area functioning as a sensing area, at least one non halide defibrillation gel layer and halide containing sensing gel layer configured to attach with the defibrillation area and sensing area respectively, and at least one insulated conductive ink line for connecting the conductor print line body to a cable that provides an electrical communication between the conductor print line body and an external equipment. When direct current runs through the conductor print line body, the large silver conductor print line area polarizes and the small Ag/AgCl conductor print line area does not polarize so that small Ag/AgCl conductor print line area senses ECG signal leading to low motion artifact.

Claims

1. An electrode arrangement for low artifact electrocardiogram (ECG) monitoring and defibrillation, comprising:

at least one conductor print line body having a large silver conductor print line area functioning as a defibrillation area and a small silver-silver chloride (Ag/AgCl) conductor print line area functioning as a sensing area;

at least one non halide defibrillation gel layer configured to attach with the defibrillation area on a bottom side of the conductor print line body;

at least one halide containing sensing gel layer configured to attach with the sensing area on the bottom side of the conductor print line body;

at least one insulated conductive ink line for connecting the conductor print line body to a cable that provides an electrical communication between the conductor print line body and an external equipment; and

whereby as a direct current (DC) runs through the conductor print line body, the large silver conductor print line area polarizes and the small Ag/AgCl conductor print line area does not polarize so that the small Ag/AgCl conductor print line area is picked up first and senses an ECG signal.

2. The electrode arrangement of claim 1 wherein a motion artifact in the ECG signal may be significantly less due to a small conductive surface area of the sensing area.

3. The electrode arrangement of claim 1 wherein the defibrillation area delivers an electrical impulse to a patient'"'"'s heart and the sensing area sequentially conveys the ECG signal from the patient'"'"'s heart to external monitoring equipment.

4. The electrode arrangement of claim 1 wherein the conductor print line body comprises a plurality of top layers including a substrate for conductor print line body, a laminating adhesive, and an insulated backing member.

5. The electrode arrangement of claim 1 wherein the conductor print line body further comprises a plurality of bottom layers including a laminating adhesive, a connection insulation, and a removable cover for skin contacting side.

6. The electrode arrangement of claim 1 wherein the defibrillation area can function as any of a plurality of other cardiac stimulation area including pacing, cardioversion, etc.

7. A method of treating a patient with an electrode arrangement for low artifact electrocardiogram (ECG) monitoring and defibrillation, comprising the steps of:

providing the electrode arrangement comprising a conductor print line body having a defibrillation area and a sensing area;

removing a cover for a skin contacting side and applying the electrode arrangement that is configured to adhesively secure to the skin of the patient;

receiving a first set of electrical impulses from an external stimulating equipment on the defibrillation area and delivering the first set of electrical impulses to a patient'"'"'s heart; and

sequentially receiving a second set of electrical impulses on the sensing area from the patient'"'"'s heart and conveying the second set of electrical impulses to an external monitoring equipment.

8. The method of claim 7 wherein the conductor print line body comprises a plurality of top layers including a substrate for conductor print line body, a laminating adhesive, and an insulated backing member.

9. The method of claim 7 wherein the conductor print line body comprises a plurality of bottom layers including a laminating adhesive, a connection insulation, and a removable cover for skin contacting side.

10. The method of claim 7 wherein the defibrillation area can function as any of a plurality of other cardiac stimulation area including pacing, cardioversion, etc.
