Embodiment 1

[0033] see figure 1. The electrocardiogram diagnosis system adopting the scheme of matching electrocardiogram includes three subsystems: database subsystem 1, application service subsystem 2 and index configuration subsystem 3.

[0034] Database subsystem 1 manages case database 4, index database 5, feature code library 6, diagnosis code library 7 and feature template library 8, etc.;

[0035] The "gold standard" ECG case is stored in the case database 4, including raw data such as patient information, detection environment information, and ECG signal;

[0036] The index database 5 is a directory created to quickly locate the storage location of ECG cases. It can be dynamically increased or decreased based on the case entity, and the index database can also be rebuilt through the index configuration subsystem 3. The case index mainly uses feature code sets and diagnostic codes The feature code index set indexes the case database according to a set of information describing t...

Embodiment 2

[0053] see figure 2 . Compared with the system in Example 1, the electrocardiogram diagnosis system using the knowledge acquisition and derivation scheme adds a knowledge management subsystem 25 to the electrocardiogram diagnosis system adopting the matching electrocardiogram scheme.

[0054] The knowledge management subsystem 25 works offline, constructs a directed graph model of "feature code→diagnostic code" by scanning the "gold standard" case database; Graphical model.

[0055] Correspondingly, the comprehensive evaluation program 21 of the application service subsystem 2 is no longer useful, and is replaced by a model deduction program 28 .

[0056] The diagnostic logic based on the "gold standard" database built in the application service subsystem 2 is changed to: after the index matching program 19 outputs the ECG feature code, it calls the model derivation program 28, and the ECG feature code can directly obtain the diagnosis result through model derivation, and t...

Abstract

The invention discloses an electrocardiogram analyzing system based on a gold standard database. The system at least comprises a database subsystem (1) and an application service subsystem (2), wherein the database subsystem (1) at least comprises a gold standard electrocardiogram case database (4) and an index database (5); the application service subsystem (2) is used for receiving electrocardiogram data to be diagnosed, which is derived from an electrocardiogram data source (12) and calculating the characteristics of an electrocardiogram to be diagnosed by waveform analysis, characteristic calculation and index matching; the application service subsystem (2) is used for retrieving the index database (5) and the electrocardiogram case database (4) by utilizing the characteristics of the electrocardiogram to be diagnosed to obtain a gold standard electrocardiogram case set which is matched with the characteristics of the electrocardiogram to be diagnosed; the system also comprises an index configuring subsystem (3); the index configuring subsystem (3) comprises an index editor (22) and an index evaluating tool (23); the system can also comprises a knowledge management subsystem (25); the knowledge management subsystem (25) is used for constructing an diagnostic model for representing a causal relationship of a characteristic code and an diagnostic code by scanning the gold standard case database (4); and the application service subsystem (2) is used for directly converting the characteristics of the electrocardiogram to be diagnosed into a diagnostic result by utilizing the diagnostic model.

Description

technical field [0001] The invention belongs to the medical and health field, and relates to an electrocardiogram automatic analysis system, in particular to an electrocardiogram analysis system based on a "gold standard" electrocardiogram database. Background technique [0002] At present, all medical electrocardiographs are required to have the automatic analysis function of electrocardiogram. Specifically, the electrocardiograph can use its own analysis program to automatically measure waveform parameters and rhythm parameters and perform diagnostic classification. After more than 30 years of development, the traditional automatic electrocardiogram analysis technology has become mature, and many foreign clinical trials have proved that the GEMarquette 12SL analysis program recommended by the US Food and Drug Administration can achieve a comprehensive reliability rate of "70-80%" ;Better than the average diagnostic level of general clinicians, an excellent ECG analysis and...
