摘要：The Heart Rate Variability signal (HRV) measures the spontaneous variability between successive beats, as they are revealed by the presence of an R wave in the Electrocardiographic ECG signal. Recent researches on HRV have suggested that besides traditional Linear analysis techniques, the Non-Linear parameters can also provide valuable information for the physiological interpretation of heart rate fluctuations. The paper focuses on a comprehensive characterization of HRV using Fractal Dimension (FD) which is computed using two different methods. First, the intrinsic relation between Detrended Fluctuation Analysis, Power Law Index and Fractal Dimension is utilized to determine the value of FD. In the second approach, the results obtained using the proposed method is established by computing the value of Fractal dimension using a standard approach as proposed by the Higuchi’s algorithm. The aim is to establish the proposed method as a standard one for computing Fractal dimension and associate it with other existing well-defined FD computation techniques. Current study amongst male and female subjects leads us to identify non-linear HRV measures that may provide powerful insights into cardio-autonomic activity.
