Abstract

A sling or jacket (10) is to be worn on the bust and comprises internally a plurality of electrocardiographic recording electrodes (V1-V10) which, when wearing, are positioned in contact with predetermined bust areas. The sling (10) comprises a pectoral part (11) supporting a first series of electrodes of the plurality, an inguinal part (28) supporting a second series of electrodes of the plurality and a scapular part (36,37) supporting a third series of electrodes of the plurality and said parts being interconnected by straps for positioning and adjustment of the spacing.

a scapular part supporting a third series of electrocardiographic recording electrodes,

said pectoral part extending laterally in a strap for fastening around a chest, and

a rear element supported by said strap supporting said scapular part between said rear element and said pectoral part,

said pectoral part, said inguinal part and said scapular part being connected to effect positioning at their respective labelled body locations.

5. Device in accordance with claim 4, wherein said pectoral part, said inguinal part, and said scapular part are interconnected by extensible connection parts to allow their adherence to the bust.

6. Device in accordance with claim 5, wherein said connection parts comprise straps for positioning and adjustment of spacing between the interconnected pectoral, inguinal, and scapular parts.

7. Device in accordance with claim 6, wherein at least one section of at least one connection strap is made of elastic material.

8. Device in accordance with claim 6, wherein at least one of the positioning and adjustment straps comprises buckles for adjustment of its length.

9. Device in accordance with claim 8, wherein said buckles comprise means of engagement made up of strips of hook and loop fabric.

10. Device in accordance with claim 6, wherein said straps comprise a pair of suspenders for passage over the shoulders.

11. Device in accordance with claim 10, wherein said third series of electrodes are each supported by one of said suspenders.

12. Device in accordance with claim 10, wherein said suspenders extend between said rear element and a front portion of the device.

13. Device in accordance with claim 12, wherein said front portion is connected in a position above said pectoral part.

14. Device in accordance with claim 13, wherein said pectoral part and said front portion are connected by a releasable connector.

15. Device in accordance with claim 14, wherein said releasable means comprises an opening ribbon fastened to said pectoral part passing through a ring supported on said front portion.

16. Device in accordance with claim 4, wherein said pectoral part is of nonextensible material to hold a spacing of the electrocardiographic recording electrodes thereon fixed.

17. Device in accordance with claim 4, wherein said first series of electrocardiographic recording electrodes comprises two electrodes located spaced for positioning near the fourth intercostal space along the right and left parasternal line respectively;

three electrocardiographic recording electrodes spaced for positioning substantially level with the fifth intercostal space along the left hemiclavate, front axillary and media lines respectively; and

an electrocardiographic recording electrode placed for positioning substantially halfway on the conjunction line of the electrode placed along the left parasternal line with the electrode placed along the left hemiclavate line when said pectoral part is positioned on a body.

18. Device in accordance with claim 4, wherein said inguinal part is of nonextensible material to hold a spacing of the electorcardiographic recording electrodes thereon fixed.

19. Device in accordance with claim 4, wherein said second series of electrocardiographic recording electrodes comprises two electrodes placed for positioning substantially opposite the two iliac fossae when said inguinal part is positioned on a body.
