Heart Rate (HR), Time warping, Electrocardiogram (ECG), Cardiac phase
In this paper the cardiac phase is calculated using different methods based on time warping theory. The estimated phase is used for calculation of the heart rate (HR) signal. The results show that the estimated HR is similar to the HR calculated by using the RR-interval sequence. Unlike the RR-interval signal which is non-uniformly sampled, the proposed method for HR calculation is continuous in time. Therefore, conventional signal processing methods can be used to study the HR signal easily and without any preprocessing techniques like resampling and interpolations used in previous method.
