【摘要】 该文以小波变换的极大值在多尺度间的变化与信号的瞬变有直接关系为基础,由小波变换的奇异点(过零点、极值点等)来观测R波,寻找它的起始点、波峰,并对常见的异常R波的选择给出了新的判别方法.实验表明,本方法对QRS(Q-wave,R-wave,S-wave)信号的提取和分析有很大的帮助.更多还原

【Abstract】 Based on the fact that maximum of wavelet transform on multiscales is related to the discontinuity of signals, Rwaves are detected and the startpoint, endpoint and peaks are located from the singularity (zerocrossings, maxima, minima, etc.) of wavelet transform. A new method of detecting singular Rwaves is given. Experiments show that the method is efficient in detection and analysis of Rwaves.更多还原
