Abstract

An electrode wearable or harness permits for easy, quick, and unsupervised administration or self-administration of a resting 12-or-more-lead ECG. Various advantageous features of the electrode wearable or harness include: inflatable or padded cushions at the lateral sides of the torso that function to press LA and RA electrodes mounted on the cushions against the downward-resting arms of the subject, permitting good electrode abutment with distal electrode placement without the need for adhesives, straps, bands, bracelets, or gloves on the arms; padding over the sternum to avoid tenting in the V₁, V₂, V₃ and V_3R electrodes whenever present, easy-to-don, one-piece design with an adjustable single point of connection and an adjustable shoulder strap; Lund or modified Lund placement; dry electrodes; and various other features. Methods of use are also described.

Claims

1. A wearable for administration or self-administration of a resting 12-or-more-lead ECG from full or reduced electrode sets, of a subject having arms and a body, the wearable comprising:

a thin flexible electrode support adapted to be worn only about the subject'"'"'s torso and having an inside in contact with the subject'"'"'s torso and an outside, the support further supporting a plurality of electrodes, including at least one precordial electrode and LA, RA, and LL electrodes, and

electrode-supporting cushions attached to or integral to the outside of the electrode support with the LA and RA electrodes attached to or integrated into the electrode-supporting cushions, the cushions placed on the electrode support such that pressure is exerted by the cushions upon the arms when the arms are placed in contact with the cushions directed downwardly in either a sideward, backward or forward direction, the pressure being sufficient to make the cushion-mounted LA and RA electrodes contact with the medial, posterior or anterior surfaces of the arms without substantial muscular exertion on the part of the subject to press the arms into the cushion-mounted LA and RA electrodes.

2. The wearable of claim 1, wherein the electrodes are dry electrodes.

3. The wearable of claim 1, wherein the wearable comprises at least one adjustable shoulder strap.

4. The wearable of claim 1, wherein the wearable is configured to be fastened about the subject'"'"'s torso only by no more than one point of connection/disconnection.

5. The wearable of claim 4, comprising one point of connection/disconnection, said point of connection/disconnection comprising a fastener of adjustable length to resize or adjust tightness so as to provide a good fitting of the wearable to the subject.

6. The wearable of claim 1, wherein the LA, RA and LL electrodes are arranged according to a Lund or modified Lund electrode placement scheme.

7. The wearable of claim 1, wherein the wearable further comprises electronic components embedded in the thin flexible electrode support that amplify, digitize, multiplex, store, and/or transmit signals from the electrodes, and said electronic components also mechanically function, along with padding in the thin flexible electrode support, to supply pressure on electrodes including the at least one precordial electrode, against the chest.

8. A wearable for administration or self-administration of a resting 12-or-more-lead ECG from full or reduced electrode sets, of a subject having a chest having a sternum, the wearable comprising:

a thin flexible electrode support adapted to be only worn upon a subject'"'"'s torso having an inside in contact with the subject'"'"'s torso and an outside, the support further supporting a plurality of electrodes, including at least one precordial electrode and LA, RA, and LL electrodes, each electrode having a respective placement site, the thin flexible electrode support comprising padding in the thin flexible support over the sternum such that any electrodes subject to tenting near the sternum are pushed down toward the chest, bringing them into good electrical contact with their respective placement sites; and

wherein no adhesives are used in fastening the wearable, electrode support, or any electrodes to the subject.

9. The wearable of claim 8, wherein the electrodes are dry electrodes.

10. The wearable of claim 8, wherein the wearable is configured to be fastened about the subject'"'"'s torso only by no more than one point of connection/disconnection.

11. The wearable of claim 10, comprising one point of connection/disconnection, said point of connection/disconnection comprising a fastener of adjustable length to resize or adjust tightness so as to provide a good fitting of the wearable to the subject.

12. A single-piece wearable for administration or self-administration of a resting 12-or-more-lead ECG from full or reduced electrode sets on a subject having arms and a body, the single-piece wearable comprising:

a thin flexible electrode support adapted to be only worn upon the subject'"'"'s torso, the support having an inside adapted to be in contact with the subject'"'"'s torso and an outside, the support further supporting a plurality of electrodes, including at least one precordial electrode located on the support to be on the subject'"'"'s chest when the support is worn by the subject, and LA, RA, and LL electrodes, the LA and RA electrodes disposed to make contact with the medial, posterior or anterior aspects of the subject'"'"'s arms, without the use of any adhesive on the subject'"'"'s body, without additional belts, bands, gloves, or bracelets other than what is provided in the thin flexible electrode support,

wherein the thin flexible electrode support has one point of connection/disconnection configured to fasten the support around the subject'"'"'s torso.

13. The wearable of claim 12, wherein the electrodes are dry electrodes.

14. The wearable of claim 12, wherein the wearable is fastened about the subject'"'"'s torso by no more than one point of connection/disconnection, and the point of connection/disconnection comprises a fastener of adjustable length to resize or adjust tightness so as to provide a good fitting of the wearable to the subject.

15. The wearable of claim 14, comprising one point of connection/disconnection wherein the fastener comprises an elongated hook.

16. The wearable of claim 12, wherein the electrodes are arranged according to a Lund or modified Lund electrode placement scheme.

17. The wearable of claim 16, wherein the wearable further comprises electrode-supporting cushions attached to or integral to the outside of the electrode support, upon which the LA and RA electrodes are mounted, attached or integrated into, the cushions being disposed on the electrode support such that pressure is exerted by the cushions upon downward-resting arms when the arms are in contact with the cushions directed in a sideward, backward or forward direction, the pressure being sufficient to make the cushion-mounted LA and RA electrodes contact with the medial, posterior or anterior surface of the arms without substantial muscular exertion on the part of the subject to press the arms into the cushion-mounted LA and RA electrodes.

18. The wearable of claim 17, wherein the subject'"'"'s chest comprises a sternum and the thin flexible electrode support comprises padding in the thin flexible support over the sternum such that any electrodes subject to tenting near the sternum are pushed down toward the chest, bringing them into good electrical contact with their respective sites.

19. The wearable of claim 18, wherein the wearable further comprises electronic components embedded in the thin flexible electrode support that amplify, digitize, multiplex, store and/or transmit signals from the electrodes, and said electronic components also mechanically function, along with the padding in the thin flexible electrode support, to supply pressure on electrodes including the at least one precordial electrode, against the chest.
