基于改进差分阈值算法的心电检测技术研究_张晓军1

used as the experimental sample． The combination of bandpass filtering and wavelet threshold fi ltering were utilized to

complete the denoising of ECG signals． The ECG signals were detected by the improved differential adaptive threshold

algorithm． The experimental results showed that the algorithm could improve the detection accuracy of Ｒ wave of ECG

signal to 99． 57% ． The algorithm effectively reduced the occurrence of false detections and missed inspections
