[Rapid identification of QRS wave based on the moving window].
A fast and accurate intelligent identification is the developing trend of electrocardiogram (ECG) research. However, there are few methods by which satisfactory results could be obtained both in speed and in accuracy. A fast identification method of QRS wave was proposed based on moving window operation in this study. An 80 ms wide moving window was employed, in which simple difference and product operations were carried out with simple and less computation, and a very good inhibition of P and T waves and other noises was realized. Then the method was investigated with data from the MIT-BIH arrhythmia database with absence of digital filtering de-noising, and the identification accuracy of QRS complex reached 99.6%. The results showed that a rapid and accurate identification of QRS complex could be realized, which would meet the requirements for studying the real-time ECG monitoring equipment.
