心电ST-T段的截取算法与系统实现
Extraction of ECG ST-T segment and its system implementation
摘要
Abstract
Electrocardiogram(ECG)is one of the basic detection programs in the diagnosis of myocardial ischemia, myo-cardial infarction and other cardiovascular diseases, in which the ST-T segment reflects the process of ventricular repolar-ization. Firstly, the wavelet transform-based Multi-Resolution Analysis(MRA)is applied to correct the baseline drift and filtering of the original ECG signals. Then, by combining the convexity operator and dynamic search window, the location of the ST-T segment is obtained. Through all the data in the European ST-T database, the average recognition rate of the algorithm is more than 93%. For all regular ECG signals, the recognition rate is above 90%. This algorithm avoids the lo-cation difficulty for T wave peak. It can be effectively applied to the problem of location of R wave inversion, T wave inversion and T wave rose changes. Furthermore, since the computation complexity of this algorithm is lower, it can be well embedded into practical engineering applications.关键词
