Embodiment Construction

[0071] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0072] The main solution of the embodiment of the present invention is to obtain the ECG signal to be processed, and determine the range of the QRS wave group in the ECG signal to be processed; within the range of the QRS wave group, determine the position of the R peak, and according to the QRS wave group The range and the determined R peak position determine the positions of the Q peak and the S peak; between the QRS complex and the adjacent QRS complex, extract the relevant information of the T wave and the P wave, and the determined range of the QRS complex , the position of the R peak, the position of the Q peak and the S peak, and the extracted relevant information of the T wave and the P wave are the characteristic information of the ECG signal to be processed, and the relevant information includes the peak posi...

Abstract

The present invention discloses an electrocardiosignal feature information extraction method. The method comprises acquiring a to-be-processed electrocardiosignal and determinging the range of a QRS complex; within the range of the QRS complex, determining the position of an R peak and determining positions of a Q peak and an S peak according to the range of the QRS complex and the R peak; and extracting relative information of a T wave and a P wave between the QRS complex and an adjacent QRS complex, the determined QRS complex, the position of the R peak, the positions of the Q peak and the S peak and the extracted relative information of the T wave and the P wave being feature information of the to-be-processed electrocardiosignal, and the relative information including wave crest positions of the T wave and the P wave and starting points and stop points of the T wave and the P wave. An an electrocardiosignal feature information extraction device is also disclosed. The acquisition of the electrocardiosignal feature information is well-adapted, and a calculated amount of electrocardiosignal feature information extraction is reduced.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method and device for extracting feature information of electrocardiographic signals. Background technique [0002] Heart disease is one of the diseases with the highest morbidity and mortality rate today. The prevention and diagnosis of heart disease has become an important issue in today's medical field. At present, electrocardiogram technology is used as an important means of heart disease diagnosis because of its advantages of simple operation method and no invasive damage to patients. [0003] The diagnostic method of the conventional electrocardiogram is: collect a short section of electrocardiogram waveform, and the doctor will read the diagram for diagnosis. This diagnostic method cannot truly reflect the condition of the heart because it only collects the ECG waveform for a short period of time. However, the traditional Holter ECG detection technology (i.e. "Dynamic...
