Abstract

There is described a wearable 12-lead ECG fabric electrode belt system having the standard 10 electrodes permitting the capture of a 12-lead ECG by using predetermined electrical vectors passing through the heart. This system is devoid of the electrodes normally present at the feet or lower pelvis area of the patient. Non-adhesive electrodes are used, which is an advantage for the skin of the patient and allows the patient the possibility of removing and repositioning the belt system if need be. All of the electrodes on the chest area are provided in a single line and positioned just below the pectoral line.

Claims

1. A belt system for collecting electrocardiogram signals, the system comprising:

a chest strap having attachment means for strapping around a chest of a patient, and eight non-adhesive electrodes mounted thereon, aligned and spaced apart on said chest strap at pre-determined positions;

a first arm strap having attachment means for strapping around a first arm or shoulder of said patient, and one non-adhesive electrode mounted thereon; and

a second arm strap having attachment means for strapping around a second arm or shoulder of said patient, and one non-adhesive electrode mounted thereon.

2. A belt system as claimed in claim 1, wherein said eight non-adhesive electrodes are spaced half an inch apart.

3. A belt system as claimed in claim 1, wherein each of said electrodes comprise a foam square covered by a conductive textile and a wire soldered to said conductive textile.

4. A belt system as claimed in claim 1, wherein said chest strap comprises two 1½

″

straps.

5. A belt system as claimed in claim 4, wherein said first arm strap and said second arm strap each comprise two 1½

″

×

2½

″

straps.

6. A belt system as claimed in claim 5, wherein each strap is made of an elastic fabric.

7. A belt system as claimed in claim 1, wherein said attachment means are hook and loop fasteners.

8. A belt system as claimed in claim 1, wherein said electrodes are mounted on said straps by snap fasteners.

9. A belt system as claimed in claim 1, further comprising a ten pin connector connected to all of said electrodes and attached to said chest belt, said ten pin connector being connectable to a device used to analyse said signals.

10. A method for collecting electrocardiogram signals on a patient, the method comprising:

aligning eight non-adhesive electrodes in a substantially straight line underneath a pectoral line of said patient, said eight non-adhesive electrodes being placed at pre-determined positions;

positioning a single non-adhesive electrode on each arm or shoulder of said patient; and

collecting bio-electrical signals from heart activity using said electrodes and sending them to a device for storage or analysis.

11. A method as claimed in claim 10, further comprising connecting all of said non-adhesive electrodes into a single ten-pin connector, and connecting said ten-pin connector to a standard electrocardiogram apparatus.

12. A method as claimed in claim 10, wherein said aligning comprises spacing each of said eight non-adhesive electrodes half an inch apart.

13. A method as claimed in claim 10, wherein said aligning comprises mounting said eight non-adhesive electrodes on an elastic fabric strap.

14. A method as claimed in claim 13, wherein said positioning a positioning comprises mounting each of said single non-adhesive electrode on an elastic fabric strap.

15. A method as claimed in claim 14, wherein each elastic fabric strap comprises a hook and loop fastener to secure onto said patient.
