心电信号R波函数系数非参数统计模型自适应Electrocardiogram (ECG) Signal; R Wave; Functional Coefficient Nonparametric Statistical Model; Adaptive Method



A novel R wave detection method is presented based on functional coefficient nonparametric statistical model. Firstly, digital bandpass filter is used for denoising and filtering of Electrocardiogram (ECG) signal. Then ECG signal is fitted by using functional coefficient nonparametric statistical model and difference threshold. Finally, the derivative of fitting model is applied to detect R wave in ECG with signal processing and threshold. Compared to the old difference method for R wave detector, the nonparametric statistical regression approach is more accurate based on the derivative of each point. Clinical data are used to test the performances. The experimental results show that the proposed method for R wave detection is effective.
