Description
Technical Field
The invention belongs to the field of electrocardiosignal acquisition and analysis technology and equipment, and particularly relates to a multichannel body surface electrocardiosignal synchronous real-time acquisition system.
Background
The conventional 12-lead body surface electrocardiogram is a traditional clinical judgment means, and has been used for analyzing and diagnosing arrhythmia for over 100 years, such as locating the origin of ventricular premature beat, the origin of atrial premature beat and the like. However, the conventional 12-lead electrocardiogram has inherent defects, such as nonstandard lead placement positions, graphic inaccuracy caused by heart transposition, thoracic cavity anatomy and individual heterogeneity of patients, low mapping accuracy and the like, and the conventional 12-lead electrocardiogram has low accuracy in arrhythmia diagnosis and the like due to limited lead number, has large heterogeneity among different judgers, and particularly cannot capture body surface information reflected on the back of a human body in time, such as specific change of the back body surface electrocardiogram during acute posterior wall and inferior wall myocardial infarction. Therefore, how to more accurately, comprehensively and effectively reflect and record the body surface electrocardiosignals by using the limited body surface electrocardio lead number is always a hotspot of the study and application of the electrocardio.
Therefore, in the beginning of the 19 th century, a body surface potential mapping technology based on a conventional 12-lead body surface electrocardiogram is produced. The technology obviously extends the application range of the standard 12-lead electrocardiogram, adopts more body surface electrodes, has wide body surface distribution range and relatively fine analysis, can obtain more, finer and more comprehensive heart electrical activity change rules than the conventional electrocardiogram, and has stronger scientific research and clinical application values. However, no mature product is available in the market at present for synchronously and real-timely acquiring multichannel and multi-lead electrocardiogram information of body surfaces and analyzing various arrhythmia. Some clinical research provides a scheme that body surface flexible electrode strips are adopted, each strip comprises 8-10 electrodes which are different, and multi-channel body surface electrocardio information is acquired in a mode of a plurality of electrode strips, but the scheme has the defects that if the device is used for scientific research, each electrode block on the strip is not actually clinically verified for acquiring weak body surface electrocardio signals, and a satisfactory scheme is not obtained for the problems of effective contact between the electrode block on the strip and a human body, effective and accurate extraction of the electrocardio signals, treatment of larger noise and clutter interference and the like. While other researches adopt a vest type scheme, a plurality of electrode blocks are arranged in the vest to collect multichannel body surface electrocardiosignals, and the problems of the electrode contact and collection accuracy, the collection point difference during the collection of different individuals and the like also exist. Meanwhile, the scheme does not adopt a well-known and effective acquisition scheme based on a Wilson electrocardiogram lead system when the body surface electrocardiogram is acquired, so that the accuracy, effectiveness and clinical application value of acquiring and obtaining signals are limited.
