ECG Interpolation Using Taut Cubic Splines

Traditional interpolation methods for the analysis of sampled ECG signals are inaccurate. Hence the application of interpolating cubic splines is of great significance. However, this class of functions in their ordinary form often does not give satisfactory results when used for non-uniformly sampled ECG signals. In the case of the uniformly sampled signal, its reconstruction using ordinary cubic splines is relatively simple. However, the model of the ECG signal obtained in this way is far from effective.
