Description
Technical Field
The invention belongs to the field of health care, and particularly relates to an electrocardiogram measuring system.
Background
The heart is the motive apparatus for the blood circulation of the human body. Before and after the heart beats, the cardiac muscle is excited, and weak bioelectric current is generated in the exciting process. Thus, each cardiac cycle of the heart is accompanied by bioelectrical changes. This bioelectrical change can be transmitted to various parts of the body surface. Because the tissues of each part of the body are different, and the distances from the heart are different, the electric potentials of the electrocardiosignals displayed on different parts of the body are also different. For a normal heart, the direction, frequency, and intensity of this bioelectrical change are regular. If the electric signals of different parts of the body surface are detected by the electrodes, amplified by the amplifier and recorded by the recorder, the electrocardiogram can be obtained. The doctor can diagnose the heart disease by comparing the recorded form, amplitude and relative time relation of every wave with the normal electrocardiogram. Such as cardiac arrhythmia, myocardial infarction, extra systole, hypertension, ectopic beating of the heart, etc. The collection and analysis of the electrocardiogram are usually performed in hospitals, and when patients with heart diseases or suspected heart diseases are subjected to electrocardiographic examination in hospitals, the hospitals usually use electrocardiographs to perform short-time electrocardiogram collection or 24-hour dynamic electrocardiogram monitors to perform long-time electrocardiogram collection and analysis. The electrocardiograph comprises 3-12 electrodes contacting with the body and an electrocardiograph host connected with the electrodes.
When a person suddenly feels discomfort of the heart and arrives at a hospital for electrocardiographic examination, the discomfort of the heart is lost, and correspondingly, doctors cannot find the cause of the heart discomfort from the electrocardiogram. Even long-term electrocardiographic acquisition using a 24-hour ambulatory electrocardiograph monitor (commonly known as HOLTER) does not necessarily find a reason. This is because the uncomfortable feeling of the heart often exists only for a short time, and the timing of capturing the electrocardiographic information data with the uncomfortable feeling is easily missed. The patient can not delay the illness state by finding the reason of the heart discomfort as soon as possible and timely carrying out symptomatic treatment, and the life of the patient can be saved to a certain extent. Therefore, when a person feels that the heart is untimely, the portable and convenient electrocardio detection instrument is used for measuring and recording the electrocardio information data of the user in time, which is a scheme for solving the problems. Which will be of great help in the diagnosis of the condition.
At present, a product Kardia brand single lead electrocardiograph of an AliveCor company on the market transmits electrocardiographic potential information with a mobile phone through ultrasonic waves, so that the problem of timeliness of measurement is solved, but the ultrasonic waves are transmitted by the ultrasonic waves, and the ultrasonic waves are interfered by the environment, so that the accuracy of the obtained electrocardiogram is influenced; in addition, only two acquisition electrodes are provided, one for each of the left hand and the right hand, and the acquisition mode can not carry out common mode rejection on the acquired electrocardio-potential signals, namely, interference signals can not be filtered, so that the accuracy of the electrocardiogram is finally influenced.
