Electrocardiogram electrode patch that can measure deformation according to body size}

The present invention relates to an electrode patch attached to the body for electrocardiogram measurement, and relates to an electrocardiogram electrode patch capable of measuring electrocardiogram according to the chest induction method according to the body size of each user.

An electrocardiogram (ECG) records an action current generated as the heart muscle contracts and extends due to the heartbeat. An electrocardiogram test is performed when a heart disease such as acute myocardial infarction, arrhythmia, or dyspnea is suspected. Electrodes are attached to the body's skin and current data detected through the electrodes are used.

In electrocardiography, there are standard bipolar limb induction method and amplified bipolar limb induction method using 4 electrodes, and chest induction method using 6 electrodes. In addition, electrocardiogram tests include a standard bipolar extremity induction method, amplified bipolar extremity induction method, and chest induction method through a 12-lead method using 10 electrodes.

In the 12-lead case, 6 of the 10 electrodes (V1 to V6) are placed near the heart, and the remaining 4 electrodes (LA, RA, RL, LL) are placed on the limbs or chest of the subject. It is attached near the limb.

Using these electrodes, 3 standard limb leads and 3 amplified limb leads (vectors) are each provided with individual leads on each of the 6 thoracic electrodes. More precisely, a lead is provided by a voltage from or between specific electrodes as follows.

LA and RA electrodes: lead I,

LL and RA electrodes: Lead II,

LL and LA electrodes: lead III;

Combination of LA and RA and LL: augmented lead vector left (aVL);

RA and combination of LA and LL: augmented lead vector right (aVR);

Combination of LL and RA and LA: augmented lead vector foot (aVF), and leads V1 to V6;

Here, the six chest electrodes may be positioned as follows.

V1: fourth intercostal space on the right side of the sternum

V2: fourth intercostal space to the left of the sternum

V3: Midpoint of the line connecting electrodes V2 and V4

V4: 5th intercostal space on the left midclavicular line

V5: level with lead V4 at the left anterior axillary line

V6: level with lead V5 at the left midaxillary line

So you get 12 measurements including leads I, II, III, aVR, aVL, aVF, V1, V2, V3, V4, V5, V6, and RL is usually the ground electrode.

Meanwhile, a 3-lead electrocardiogram electrode patch as disclosed in No. 10-2014-0050374 has been developed and used in response to various electrocardiogram test methods, and a 12-lead electrocardiogram electrode patch as disclosed in No. 10-1780926 has been developed and used.

However, in the prior art, an electrode patch for 3-lead electrocardiography is provided to a subject for 3-lead electrocardiography, and an electrode patch for 3-lead electrocardiogram is provided to a subject for 12-lead electrocardiography. Since electrode patches are provided, it is inconvenient to have each electrode patch for each type of inspection.

In addition, it is common for each test subject to have a different chest size depending on the body size. Nevertheless, the current 12-lead electrocardiogram electrode patch is manufactured in a form in which the position between the electrodes is fixed, so there is a problem in that the electrodes cannot be accurately attached to the positions of V1 to V6 to suit each test subject with a different chest size. .
