Abstract—In this paper a comparative study of linear and non-linear analysis methods, for deciphering the hidden dynamics of heart rate variability in young women during follicular and luteal phase of menstrual cycle, has been performed. In this study 25 healthy young women in the age of 18 to 25 years have been participated. The non-linear analysis methods used are: approximate entropy and largest lyapunov exponent and autoregressive method is used as a linear analysis method. The results confirmed that the heart rate variability is more in the follicular phase as compared to luteal phase of menstrual cycle. Further it has been found that the linear analysis method is not been able to differentiate between these two phases of menstrual cycle in comparison to non-linear analysis methods. Hence, approximate entropy and largest lyapunov exponent methods interpret the complexity of heart rate more significantly than an autoregressive method.
