Abstract

The analysis of heart rate variability (HRV) is an important tool for the assessment of the autonomic regulation of circulatory function. HRV analysis is usually performed using methods that are based on the assumption that the signal is stationary within the RR interval duration (up to 24 hour per patient), which is generally not true for long duration signals. Analysis and evaluation of Electrocardiography(ECG) arrhythmia data can be processed by the method of time methods, frequency methods and nonlinear methods. Detrended fluctuation analysis (DFA), afractal analysis method which is widely used in heart rate variability studies, is used to analyze the scaling behavior of RR interval series of preterm neonates. In this paper, we improve the DFA algorithm to MDFA (MultiDetrended fluctuation analysis) to evaluate the possibility of arrhythmias RR intervals detail for each period of 20 minutes in entire RR intervals. Evaluation results are shown graphically intuitive with three levels of basic arrhythmia arrhythmia is high, medium and low arrhythmia.
