Abstract EN
R-peak detection is crucial in electrocardiogram (ECG) signal analysis.
This study proposed an adaptive and time-efficient R-peak detection algorithm for ECG processing.
First, wavelet multiresolution analysis was applied to enhance the ECG signal representation.
Then, ECG was mirrored to convert large negative R-peaks to positive ones.
After that, local maximums were calculated by the first-order forward differential approach and were truncated by the amplitude and time interval thresholds to locate the R-peaks.
The algorithm performances, including detection accuracy and time consumption, were tested on the MIT-BIH arrhythmia database and the QT database.
Experimental results showed that the proposed algorithm achieved mean sensitivity of 99.39%, positive predictivity of 99.49%, and accuracy of 98.89% on the MIT-BIH arrhythmia database and 99.83%, 99.90%, and 99.73%, respectively, on the QT database.
By processing one ECG record, the mean time consumptions were 0.872 s and 0.763 s for the MIT-BIH arrhythmia database and QT database, respectively, yielding 30.6% and 32.9% of time reduction compared to the traditional Pan-Tompkins method.
