## Abstract

An electrocardiogram measurement device according to an aspect of the present disclosure is a portable electrocardiogram measurement device, and the electrocardiogram measurement device includes: a first electrode disposed at a position that can be touched with one upper limb of a measurement subject; a second electrode disposed at a position that can be touched with the other upper limb of the measurement subject; a calculation unit that calculates a potential difference between the first electrode touched with the one upper limb of the measurement subject and the second electrode touched with the other upper limb of the measurement subject; a guide unit that generates guidance information to guide the measurement subject to bring the other upper limb into contact with a predetermined portion of the second electrode; and a display unit that displays the potential difference calculated by the calculation unit and/or the guidance information generated by the guide unit.

## Claims

### Claim 1

An electrocardiogram measurement device being portable, the electrocardiogram measurement device comprising:
a case;
a belt;
a plurality of first electrodes each disposed at a respective position touchable with one upper limb of a measurement subject;
a plurality of second electrodes each disposed at a respective position touchable with the other upper limb of the measurement subject;
a calculation unit configured to calculate a potential difference between one of the plurality of first electrodes touched with the one upper limb of the measurement subject and one of the plurality of second electrodes touched with the other upper limb of the measurement subject;
a guide unit configured to generate guidance information to guide the measurement subject to bring the other upper limb into contact with a predetermined portion of the one of the plurality of second electrodes;
a display unit configured to display the potential difference calculated by the calculation unit and/or the guidance information generated by the guide unit;
a detection element configured to detect a gravitational acceleration component in a predetermined direction,
wherein the guide unit generates the guidance information based on the gravitational acceleration component in the predetermined direction detected by the detection element; and
a blood pressure measurement unit configured to measure blood pressure,
wherein the guide unit further generates guidance information related to a height of the blood pressure measurement unit,
wherein the plurality of first electrodes includes a left-hand electrode being disposed on a left edge of the case when the display is viewable and a left-hand electrode being disposed on the surface of the belt that is configured to be brought into contact with skin of the measurement subject,
wherein the plurality of second electrodes includes a right-hand electrode being disposed on a lower edge of the case when the display is viewable and a right-hand electrode being disposed on a right edge of the case when the display is viewable, and
wherein the guide unit further generates guidance information related to a combination of the plurality of first electrodes and second electrodes to be contacted according to an operation mode.

### Claim 2 (depends on 1)

The electrocardiogram measurement device according to claim 1, further comprising an attachment portion configured to be attached on at least one of the one upper limb and the other upper limb of the measurement subject; and
a first determination unit configured to determine, based on the gravitational acceleration component in the predetermined direction detected by the detection element, whether the electrocardiogram measurement device is attached on the measurement subject,
wherein the guide unit generates the guidance information based on a determination by the first determination unit.

### Claim 3 (depends on 2)

The electrocardiogram measurement device according to claim 2, further comprising a second determination unit configured to determine, based on the gravitational acceleration component in the predetermined direction detected by the detection element, an upper limb on which the electrocardiogram measurement device is attached among the one upper limb or the other upper limb,
wherein the guide unit generates the guidance information based on a determination by the second determination unit.

### Claim 4 (depends on 2)

The electrocardiogram measurement device according to claim 2, wherein the guide unit generates the guidance information indicating two locations touchable by different fingers of one hand.

### Claim 5 (depends on 1)

The electrocardiogram measurement device according to claim 1, wherein the display unit includes a light-emitting element, and
the light-emitting element is disposed at or near the predetermined portion.

### Claim 6 (depends on 1)

The electrocardiogram measurement device according to claim 1, wherein the plurality of second electrodes are three or more electrodes.
