Abstract

A measuring system for measuring electrocardiogram signals comprises a diagnostic garment with ECG electrodes that may assume the form of a sleeve or glove. A disposable version of the glove can be inflated. By using an inflatable glove, the contour of the body is automatically matched by the contour of the glove. Samples from the ECG electrodes positioned on a diagnostic garment are compensated so that the samples better approximate samples from EEG electrodes that are positioned at classical locations. Also, samples from ECG electrodes are compensated to reduce signal noise resulting from positioning the ECG electrodes on the diagnostic garment.

Claims

1. A disposable diagnostic garment for obtaining human electrocardiogram (ECG) input readings comprising, in combination:

a garment comprising a flexible and inflatable material in a form substantially matching an arm and hand contour body portion of a patient, the inflatable material of said garment having an inside palm side and a connected left arm portion side, said garment further including a support sling for maintaining said garment positioned on a patient; and

at least one electrode that is affixed the inside palm side of the garment material, wherein the at least one electrode is arranged on the garment material to position the at least one electrode against the palm of the patient and provide a corresponding ECG signal when the garment material is inflated and when the left arm is supported by said sling with the left elbow substantially against the body of a patient and the left forearm directed substantially toward the right shoulder, and wherein the at least one electrode comprises a V₁ or a V₂ electrode.

2. The disposable diagnostic garment of claim 1, wherein the garment comprises a hand portion for a left hand of the patient, and wherein the at least one electrode comprises one or more of RA, RL, V1, and V2 electrodes.

3. The disposable diagnostic garment of claim 1, wherein the at least one electrode is affixed to the garment by depositing a conductive material on the garment.

4. The disposable diagnostic garment of claim 1, wherein the garment comprises a plastic material.

5. The disposable diagnostic garment of claim 1, further comprising:

an inflation means for inflating the disposable diagnostic garment.

6. The disposable diagnostic garment of claim 1, further comprising:

a one-way valve for inflating the disposable diagnostic garment.

7. The garment of claim 6 wherein said garment is comprised of at least two inflatable pillow members for inflation by a gas.

8. The garment of claim 1 wherein said pillow members are interconnected.

9. The garment of claim 8 wherein an electrode is mounted on separate pillow members.

10. The garment of claim 6 further including an adhesive on at least a portion of said garment covering for maintaining said garment on a body portion.
