Detection of ST segment in electrocardiogram signal based on two-dimensional cloudy model theory
摘要
Abstract
BACKGROUND: There is no precise classificated mathematical model and identification standard for the morphological characteristics of abnormal ST segment, and therefore, the improvement of automatical recognization wil be limited in some cardiovascular diseases diagnoses. OBJECTIVE: To find a new method meeting the medical diagnosis logical thinking for analyzing the ST segment in electrocardiogram signal, and to provide new ideas for real-time analysis of the changes of electrocardiogram of ST segment. METHODS: A new algorithm for detecting ST segment in electrocardiogram signal based on two-dimensional cloudy model theory was proposed in view of the fuzziness and randomness of electrocardiogram signal. And then, it estimated the membership grade of two-dimensional cloud generator and identified the morphology of ST segment in electrocardiogram. RESULTS AND DISCUSSION: The algorithm was simulated with Matlab, and the algorithm accuracy was verified by standard ECG database (European Community CSE database). The statistical results showed that the algorithm had a high identification rate of ST segment, and it was shortcut and effective for processing the large amount of data which provide a new method for the accurate analysis of the ST segment.关键词
