Inter-beat (R-R) intervals analysis using a new time delay estimation technique

In this paper, a new time delay estimation technique is applied for the R-R interval analysis. The key idea is about the R-R interval estimation of the ECG signal that is regarded as a time delay estimation in which we cast the change-point detection problem. This work aims to present an ad-hoc time delay technique that stems from operational calculus, differential algebra and non commutative algebra. So, we will be able to identify the change-point location and consequently the delay. Consequently, the R-R intervals estimation is deduced from a time delay estimation. The experimental results are provided and discussed to illustrate the efficiency of the proposed method under the real case. Tests are performed according to the recordings from MIT-BIH arrhythmia database. Moreover, the issues of the proposed algorithm robustness which is compared to literature are examined.
