Electrode patch for health monitoring
A method of measuring bioelectric signals of a patient having an axis extending from the patient's head to the patient's feet includes attaching a patch to the patient's skin. The patch may include a first electrode and a second electrode spaced apart along a longitudinal axis of the patch. The patch may be attached such that the longitudinal axis of the patch is generally aligned with the axis of the patient. The method may also include attaching a third electrode to the patient's skin, and measuring bioelectric signals of the patient using the first electrode, the second electrode, and the third electrode.
1. A method of measuring bioelectric signals of a patient having an axis extending from the patient's head to the patient's feet, comprising:
attaching a patch to the patient's skin at a first location, the patch including a first electrode and a second electrode spaced apart along a longitudinal axis of the patch, the patch being attached such that the longitudinal axis of the patch is generally aligned with the axis of the patient, wherein the first location is under an arm of the patient;
attaching a third electrode to the patient's skin at a second location, wherein the third electrode is separate from the patch, and the second location is different from the first location; and
measuring bioelectric signals of the patient using the first electrode, the second electrode, and the third electrode.
2. The method of claim 1 , wherein the bioelectric signals include ECG signals.
3. The method of claim 1 , wherein attaching the patch includes attaching the patch under an arm pit of the patient.
4. The method of claim 3 , wherein attaching the third electrode includes attaching the third electrode above the right atrium of the patient's heart.
5. The method of claim 1 , further including electrically connecting the first electrode, the second electrode, and the third electrode to a portable monitor, and using the monitor to measure the bioelectric signals.
6. The method of claim 5 , further including attaching the monitor to the patch.
7. The method of claim 1 , wherein attaching the patch to the patient's skin includes attaching the patch to a thoracic region spanning about 15° on either side of a linear axis extending through the patient's outstretched arms.
8. A method of measuring ECG signals of a patient including an axis extending from the patient's head to the patient's feet, comprising:
attaching a patch under the left armpit in the patient's thoracic region, the patch including a first electrode and a second electrode spaced apart along a longitudinal axis of the patch, the patch being attached such that the longitudinal axis is generally aligned with the axis of the patient;
attaching a third electrode to a chest of the patient, wherein the third electrode is separate from the patch; and
measuring ECG signals using the first electrode, the second electrode, and the third electrode.
9. The method of claim 8 , further including electrically connecting the first electrode, the second electrode, and the third electrode to a portable monitor, and using the monitor to measure the ECG signals.
10. The method of claim 9 , further including attaching the monitor to the patch.
11. The method of claim 9 , wherein the monitor is attached to the patch between the first electrode and the second electrode.
12. The method of claim 9 , wherein attaching the patch includes attaching the patch to a thoracic region spanning about 15° on either side of a linear axis extending through the patient's outstretched arms.
13. The method of claim 9 , wherein electrically connecting the third electrode to the portable monitor includes directing measured signals from the third electrode to the patch.
14. The method of claim 8 , wherein the patch includes an adhesive layer on a surface covered by a protective strip, and the method further includes removing the protective strip prior to attaching the patch.
15. The method of claim 8 , wherein attaching the third electrode includes attaching the third electrode above the right atrium of the patient's heart.
16. A method of measuring bioelectric signals of a patient having an axis extending from the patient's head to the patient's feet, comprising:
attaching a patch to the patient's skin under an arm, the patch including a first electrode and a second electrode spaced apart along a longitudinal axis of the patch, the patch being attached such that the longitudinal axis of the patch is generally aligned with the axis of the patient;
attaching a third electrode to the patient's skin above the patient's heart, wherein the third electrode is separate from the patch; and
measuring bioelectric signals of the patient using the first electrode, the second electrode, and the third electrode.
17. The method of claim 16 , wherein attaching the third electrode includes attaching the third electrode above the right atrium of the patient's heart.
18. The method of claim 16 , wherein the bioelectric signals include ECG signals.
19. The method of claim 16 , further including electrically connecting the first electrode, the second electrode, and the third electrode to a portable monitor, and using the monitor to measure the bioelectric signals.
20. The method of claim 16 , further including attaching a monitor to the patch, and using the monitor to measure the bioelectric signals.
