Abstract

The invention relates to an arrangement for recording ECG signals. The arrangement has at least three electrodes, which can be connected or are connected to an amplification unit via lines, with at least two lines having no or essentially only a minimal distance from one another at least over one part of their length and being embodied as a component of a cable comprising more than two lines.

Claims

1. A device for minimizing an interfering induced voltage when recording an ECG signal of an object, comprising:

an amplification unit;

a plurality of electrodes that record the ECG signal of the object and that are each individually configured to be placed on an object;

a plurality of lines that each individually connect to an individual electrode of the electrodes to the amplification unit configured to be flexible to allow for independent and separate placement of each individual electrode on the object;

a cable that comprises part of length of at least two lines of the plurality of lines and remaining part of length of the at least two lines extending from the cable; and

an elastic membrane formed between the plurality of lines after the cable configured to exert a reset force on the plurality of lines when each electrode of the plurality of electrodes is individually, independently, and separately placed on the object to reduce inductive voltage;

wherein the cable minimizes a distance between the at least two lines of the part of length in the cable; and

wherein the cable maintains a minimum or no distance between the plurality of lines of the part of length of in the cable and the remaining part of length of the plurality of lines extending from the cable are configured to be placed independently and separately from one another.

2. The device as claimed in claim 1, wherein the at least two lines of the cable have a minimal distance between each other over a length of the at least two lines.

3. The device as claimed in claim 1, wherein the part of length of the at least two lines is a length from the amplification unit to a branching point.

4. The device as claimed in claim 3, wherein the branching point is located at or in a vicinity of one of the electrodes.

5. The device as claimed in claim 4, wherein the at least two lines have a same length between the branching point and the each individual electrode connected to each respective line.

6. The device as claimed in claim 4, wherein the at least two lines have a different length between the branching point and the each individual electrode connected to each respective line.

7. The device as claimed in claim 1, wherein the at least two lines are elastically connected to one another over a length of the at least two lines.

8. The device as claimed in claim 1, wherein the elastic membrane comprises an elastic belt and/or an elastic surface.

9. The device as claimed in claim 8, wherein the elastic belt and/or the elastic surface is detachable and/or removable.

10. A method minimizing an interfering induced voltage when recording an ECG signal of an object, comprising:

independently, separately and individually placing at least two electrodes of a plurality of electrodes on an object;

providing a cable comprising part of length of at least two lines of a plurality of lines and remaining part of length of the at least two lines extending from the cable, wherein the at least two lines are individually connected to the at least two electrodes, and wherein the cable minimizes a distance between the at least two lines of the plurality of lines of the part of length in the cable; and

exerting a reset force between the at least two lines by elastically connecting the at least two lines after the cable to further minimize distance between the at least two lines when the electrodes are independently and separately placed from each other to reduce an interfering inductive voltage.

11. The method as claimed in claim 10, wherein the at least two lines have a minimal distance from each other over a length of the at least two lines.

12. The method as claimed in claim 10, wherein the length is from the amplification unit to a branching point.

13. The method as claimed in claim 10, wherein the branching point is located at or in a vicinity of one of the electrodes.
