Abstract:
QRS complex has its distinct characteristics as compared with other waves in Electrocardiogram (ECG). In this paper is introduced a kind of algorithm to identify the R waves, which combines forward-backward difference algorithm, half-wave width algorithm and R-R interval algorithm. The algorithm is simple and reliable. It is in possession of the ability of anti-interference such as baseline drifting, high P waves or high T waves, and severe high-frequency interference. The average accuracy for identification is higher than 99.5%. The results of the experiment and the analyses are also presented.
