Problems solved by technology

[0003] At present, the existing electrocardiograph equipment does not have the function of judging and indicating the quality of ECG signals. The quality of the collected ECG signals is completely visually perceived through the user's clinical experience. In actual clinical applications, it is easy to collect poor-quality ECG waveforms, and no warning prompts are provided before printing the ECG report, which often leads to the printed ECG report not meeting the clinical diagnosis requirements. In some cases, users can only re-collect and re-print the ECG report, repeating operations and wasting paper, which cannot meet the user's needs for efficient work and cost saving

Abstract

The invention relates to an electrocardio signal quality determination indication method and system. The method comprises collecting human body electrocardio signals through electrodes to obtain electrocardio waveforms of corresponding leads of all physiological electrodes and the noise type and noise strength; determining the signal quality of each lead according to the noise strength of each lead, and setting sub-lead signal quality zone bits; determining the main lead signal quality according to the sub-lead signal quality zone bits and setting the main lead signal quality zone bit; setting signal quality color indication zone bits according to the main lead signal quality zone bit and setting indication signal quality signal lamps. By means of the method and the system, users can determine whether the collected electrocardio signal quality is good, and accordingly, the work efficiency of electrocardiographic examination is improved.

Description

technical field [0001] The invention relates to a method for judging and indicating the quality of a signal, in particular to a method and system for judging and indicating the quality of an electrocardiographic signal. Background technique [0002] As an embedded diagnostic medical device for ECG examination, the electrocardiograph is the most basic clinical requirement for electrocardiographs to collect and obtain the patient's ECG signal, and the quality of the ECG signal directly affects the aesthetics and readability of the waveform in the electrocardiogram report. In terms of reliability and analyzability, the best waveform that meets the requirements of clinical diagnosis requires no or little interference. However, in the actual process of collecting ECG signals, the patient's activities and non-effective electrical signals from the external environment can easily introduce interference, resulting in poor signal quality such as baseline drift and more glitches in the...
