Embodiment Construction

[0040] Such as figure 1 As shown, the electrocardiogram computer-aided diagnosis system of the present embodiment includes the following parts: characteristic parameter calculation and symbolization processing device 1, symbol set 2, intermediate reasoning result memory 3, inference engine 4, symbolized diagnosis rule base 5, physician diagnosis A rule base 6 , a preliminary diagnosis conclusion storage device 7 , a conflict resolution processing device 8 , a conflict resolution rule base 9 , and a final result output device 10 .

[0041] Symbol set 2 is used to store abstracted symbols based on the parameters used in electrocardiogram diagnosis; symbol set 2 is formed in the collation of physicians’ clinical diagnosis experience database 6, which summarizes the original physician’s diagnosis experience database and abstracts less relevant descriptions symbols, so that the expression of the entire rule base can be expressed with fewer unified symbols. A symbol set is a collec...

Abstract

The invention discloses CAD (Computer-Aided Diagnosis) system and method of an ECG (Electrocardiogram). The method comprises the following steps of: (A1) receiving an ECG signal and calculating the characteristic parameters of the ECG signal; (B1) confirming a symbolic value of each characteristic parameter according to symbolic values defined to ECG diagnosis parameters in a symbol set; (C1) reasoning and determining a symbolized diagnosis rule in a diagnosis rule library according to the symbolic values of the characteristic parameters and confirming an initial diagnosis result; and (D1) identifying and analyzing the category of the initial diagnosis result according to the contents of a conflict resolution rule library in which the identification relation of easily-confused category questions and the prioritization relation of the category questions are defined so as to optimize the diagnosis result. By separating a diagnostic reasoning process into two stages: an initial diagnosis stage and an impact resolution stage, the invention improves the reliability of ratiocination results, is simple and clear in the whole ratiocination process, can identify a great amount of pathological signals, and is convenient to maintain, upgrade and improve the whole diagnosis system.

Description

【Technical field】 [0001] The invention relates to the field of electrocardiogram signal processing, in particular to a system and method for computer-aided diagnosis of electrocardiogram. 【Background technique】 [0002] The computer-aided diagnosis and analysis of electrocardiogram is to automatically analyze the electrocardiogram signal, and give the commonly used clinical diagnostic parameters and possible diagnostic results for the reference of doctors. The research on computer-aided diagnosis of electrocardiogram began in 1960. At first, it was only used for laboratory research, and then it was gradually accepted by clinicians. At present, some programs have been used for commercial sales. The relevant methods can be roughly divided into two research routes: one is to use pure engineering analysis methods to construct certain parameter indicators for identification or prediction of specific pathological signals, such as the complexity index for ventricular fibrillation d...
