R Wave Extraction Based on the Maximum First Derivative plus the Maximum Value of the Double Search

R-wave detection is the main approach for heart rate variability analysis and clinical application based on R-R interval.The maximum first derivative plus the maximum value of the double search algorithm is applied on electrocardiogram (ECG) of MIH-BIT Arrhythmia Database to extract R wave.Through the study of algorithms characteristics and R-wave detection method,data segmentation method is modified to improve the detection accuracy.After segmentation modification,average accuracy rate of 6 sets of short ECG data increase from 82.51% to 93.70%,and the average accuracy rate of 11 groups long-range data is 96.61%.Test results prove that the algorithm and segmentation method can accurately locate R wave and have good effectiveness and versatility,but may exist some undetected problems due to algorithm implementation.
