The Chinese Pat With Ecg Database Building

As the development of ECG monitoring technology, more and more ECG machines have been equipped with ECG automatic diagnosis system. Prior to entering the market, the quality control department of the Medical Devices should do performance evaluation on the ECG machines. The International Electrotechnical Commission (IEC) has clearly indicated in its standard that, the standard database used to evaluate the ECG automatic diagnosis algorithm should be based on the population of its target market. The objective of this work is just establishing this kind of standard evaluation database from Chinese population.The data source of this work contains1200holter ECG records which were collected from Peking Union Medical College Hospital between1995and2000. By database querying and referencing to the ECG medical features, the most representitive ECG segments have been selected for the following annotation process. The ECG data format in this work is based on widespread MIT-BIH data format, which the ECG machine inspectors and researchers can apply it with opensource software to ECG waveform reviewing, ECG data analysis and process, and interconversion between different data formats.A set of annotating tools designed for clinicians has also been assembled and installed in removable storage devices. So the clinicians can use it to finish the annotating work. The removable storage can be flash memory disk or portable hard drive, which can be installed with Ubuntu operation system and annotation software. This toolkit is applicable on any PC desktop or notebook. All of the relavant software, initial data, intermediate results and finial results would be stored in the removable storage devices, which can be both safe and easy for clinicians to do their annotating work.Finially, after comparing, analyzing and processing the annotation results from clinicians, the Chinses beat-by-beat annotated ECG database has been established, which consists of65ECG segments with a length of30minutes10seconds. The finial annotation files have covered all the types of heart beats in IEC standard, which include "N","S","V","F","Q" and "U". According to the standard from IEC, this database can be used as the standard testing sample set for the quality evaluation of pre-sale ECG devices in China.
