Title: Research of Wavelet Transformation Based Detection of QRS Complex in ECG
Abstract: In this paper is presented a technique of feature extraction for QRS complex detection by using wavelet transformation based multi scales decomposition, which is robust for time varying characteristics of QRS complex and for some common kinds of EC interference. In this paper, we present a method of using two different kinds of wavelets as mother wavelet, to decompose noisy ECG signals of multi scales without pre processing of noise reduction. The results obtained were rather accurate. It was fast to detect the information in QRS waves. The algorithm was verified with records contained in MIT BIH EC database, which is widely and internationally accepted.
