Abstract

A device for acquiring electric signals of the human body from a patient'"'"'s heart includes at least two independent connection elements that each has supports that are provided each with electrodes. The electrodes are attached to an electric cable with parallel strands, which is connected to an input of an acquisition card that receives and transmits, free of electromagnetic interference, electric signals derived from the electrodes to a central unit for data processing, analyzing and editing.

Claims

1. A method of acquiring electric signals from a human patient that permits suppression of electromagnetic disturbances, comprising the steps of:

providing an acquisition card that sends signals from a human patient to an electrocardiograph;

connecting a first connection element to the acquisition card, the first connection element having plural first electrodes and a first cable that includes plural first wires that are each connected to a respective different one of the first electrodes and that are parallel to each other between the respective first electrodes and the acquisition card;

connecting a second connection element to the acquisition card, the second connection element having plural second electrodes and a second cable that includes plural second wires that are each connected to a respective different one of the second electrodes and that are parallel to each other between the respective second electrodes and the acquisition card;

attaching the first connection element to the human patient, a first set of at least two of the first electrodes being attached to a right side of the human patient relative to a sternum of the human patient and a second set of at least two of the first electrodes being attached to a left side of the human patient relative to the sternum, wherein all of the first electrodes of one of the first and second sets are arranged consecutively on a first portion of the first cable that does not cross the sternum; and

attaching the second connection element to the human patient, one of the second electrodes being attached below the heart of the human patient and a third set of at least two of the second electrodes being attached to the human patient along a line extending downward away from the heart,

whereby electromagnetic disturbances are suppressed.

2. The method of claim 1, further comprising the step of mounting each of the first and second electrodes on a respective separate support that is separately positioned on the human patient.

3. The method of claim 2, wherein one of the first and second sets of the first electrodes, other than the set arranged consecutively on the first portion of the first cable, includes ones of the first electrodes that are separated from each other along the first cable by the first portion.

4. The method of claim 1, further comprising the step of mounting the first set of the first electrodes on a single first support that is attached to the right side of the human patient and mounting the second set of the first electrodes on a single second support that is attached to the left side of the human patient.

5. The method of claim 4, wherein one of the first and second sets of the first electrodes, other than the set arranged consecutively on the first portion of the first cable, includes ones of the first electrodes that are arranged consecutively on a second portion of the first cable that is separate from the first portion and that does not cross the sternum.

6. The method of claim 4, further comprising the step of mounting the third set of the second electrodes on a single third support that is attached to the human patient along the line extending downward to the right side of the human patient.
