Technical Field

The invention belongs to the technical field of wearable electrocardiogram monitoring equipment, and particularly relates to a wearable multi-lead dynamic electrocardiogram monitor.

Background

The wearable multi-lead electrocardio sensor aims to lead the electrocardio detection technology to go from hospitals to thousands of households, and collect dynamic electrocardio signals of patients in a wearing mode, thereby realizing the aim of uninterrupted electrocardio signal detection and analysis for 24 hours. The equipment is complementary with the current medical short-term electrocardio examination method, can be used for capturing sudden physical discomfort caused by unknown reasons in real time for a long time, finds abnormal conditions of the heart in time and prompts the patient to pay attention and seek medical advice. The existing wearable dynamic electrocardiogram monitoring equipment can be divided into a single-lead type and a multi-lead type according to the number of channels. The electrocardiosignals are vectors with sizes and directions, but most of the existing dynamic electrocardio monitors are single-lead devices, only single-dimensional electrocardio information can be obtained, and the accuracy and the comprehensiveness are limited. Compared with single-lead electrocardio equipment, the multi-lead electrocardio equipment can obtain the electrocardio information of multiple dimensions, monitor the electrocardio condition of a human body more comprehensively and judge the pathological change position of the heart. However, the conventional multi-lead ambulatory electrocardiograph monitor is based on a clinically used 12-lead system, and the four limb electrodes have a large distribution range, which brings many difficulties to the development and use of a household wearable multi-lead electrocardiograph monitor, mainly including:

the conventional multi-lead system has multiple electrodes and wide distribution range, not only causes difficulty in placement and fixation of the electrodes, but also easily causes the problems of arrangement, winding and storage of lead wires.

Secondly, the electrodes are distributed and dispersed, and are more easily interfered by movement.

Three, the existing multi-lead electrocardiograph includes a plurality of (at least 4) electrocardiograph electrodes, usually with clothes as a carrier, using wearable electrodes represented by fabric electrodes. Mainly based on the clothing (such as tight clothing) of high elasticity surface fabric designs, restricts the electrocardio electrode on the skin surface with the help of the elasticity of clothing. The tightness degree of the high-elasticity clothes is closely related to the body shape and the wearing habit, the universality is limited, the comfort is poor, the high-elasticity clothes are particularly not suitable for monitoring the sleep state, and the tightness of wearing is difficult to avoid while the close fit of a plurality of groups of electrodes and the skin is ensured.

And the shapes and wearing habits of human bodies are different, and the electrode positions in the multi-lead electrocardio-coat are relatively fixed and difficult to flexibly adjust, so that a single device is difficult to adapt to different people at the same time.

Fifthly, the multi-lead ECG monitor using clothes as a carrier cannot meet the requirements of users on diversity and individuation wearing. In addition, because the multi-lead electrocardio-coat has more lead wires, the wearing comfort is also reduced.

Detailed Description

The present invention will be described in further detail with reference to the following examples and the accompanying drawings.

The potential difference formed by the myocardial cells in the process of depolarization or repolarization has both magnitude and direction, and is called an electrocardiogram vector. The projections of the electrocardiogram vectors on different lead coupling shafts form the electrocardiogram of each lead. The multi-lead electrocardiogram reflects the change of the size and direction of the instantaneous comprehensive electrocardiogram vector. The limb electrode placing parts of the conventional 12-lead dynamic electrocardiogram are respectively as follows:

RA electrode at right subclavian extrafossa 1/3;

LA electrode at 1/3 outside the left subclavian fossa;

LL electrode at the 7 th costal margin of the left mid-clavicular line;

the RL electrode is at the 7 th costal edge of the right mid-clavicular line;

a triangle formed by the RA electrode, the LA electrode and the LL electrode is called an Einthoven triangle, and a frontal plane six-axis lead system is formed.

In the invention, the position of the LA electrode is kept unchanged, and the RA electrode and the LL electrode are respectively moved in proportion to the LA electrode, wherein the RA electrode is horizontally moved to the middle line position of the sternum, and the electrode on the sternum is less susceptible to the muscle activity; accordingly, LA is moved up to the fifth rib; the right leg drive electrode RL is moved to the mid-sternum line. The triangle formed by the three groups of electrodes after moving is basically similar to the triangle formed before moving, so that a reduced version lead system still based on a frontal plane six-axis lead system is formed, the basic characteristics (waveform direction, relative strength and the like) of each lead electrocardiogram can be maintained, and the distribution range of the electrocardio-electrodes is greatly reduced. The RL electrode is used as the right leg driving electrode, mainly for improving the quality of the electrocardiogram, and does not affect the characteristics of the electrocardiogram, so that the position of the RL electrode can also move towards the LA direction. As shown in fig. 1, the electrode positions of the contracted limbs in the present invention are:

LA electrode at 1/3 outside the left subclavian fossa;

the LL electrode was at the 5 th costal margin at the left mid-clavicular line;

the RA electrode is in the midline of the sternum and is level with LA;

the RL electrode intersects the 5 th costal margin at the midline of the sternum.

In addition, the chest lead takes the central electric end as the negative electrode and the chest electrode as the positive electrode, and in the reduced lead group, the position of the chest lead electrode is kept unchanged, so that the electrocardiographic waveform which is consistent with the standard lead height can be obtained.
