Problems solved by technology

[0003] Existing electrocardiogram equipment only has the function of lead signal acquisition and does not have the function of lead signal quality evaluation. to judge
Moreover, during the acquisition process of the lead signal, the quality of the lead signal is easily affected by human factors and environmental factors, so the lead signal with poor quality can only be re-acquired, which not only reduces the electrocardiogram equipment. The effectiveness and practicality of the lead signal acquisition system, but also reduces the reliability of the collected lead signal

Abstract

The invention provides a quality judgment method for electrocardiogram. The method comprises the following steps: receiving a 12-lead signal forming electrocardiogram; judging whether the electrocardiogram is valid or not according to the 12-lead signal; and judging the quality of the electrocardiogram according to the 12-lead signal if the electrocardiogram is valid. The invention further provides a quality judgment system for electrocardiogram. When the quality judgement system and quality judgement method for electrocardiogram are applied to electrocardiogram equipment, the electrocardiogram equipment has a lead signal collection function and a lead signal quality judgment function. Furthermore, according to the quality judgement system and quality judgement method, the electrocardiogram of which the quality does not achieve a preset standard is graded, so that important information of the electrocardiogram of which the quality does not achieve the preset standard can be better maintained.

Description

technical field [0001] The invention belongs to the technical field of electrocardiogram judgment, and in particular relates to a quality judgment method and a quality judgment system of an electrocardiogram. Background technique [0002] A lead signal constituting an electrocardiogram (ECG for short) is a weak biological signal, wherein the lead signal will be subjected to electromagnetic interference from the body and instruments during the collection process to generate noise. For doctors, the worst-quality ECGs can be ignored and taken again; the poorer ones can be roughly used to diagnose disease. However, for a computer, the quality of the electrocardiogram has a greater impact on the diagnosis of a disease. Therefore, it is necessary to judge the quality of lead signals before preprocessing, feature extraction and disease diagnosis of ECG. [0003] Existing electrocardiogram equipment only has the function of lead signal acquisition and does not have the function of...
