Abstract
In this research, our aim is to calculate Fractal Dimension (FD) to analyse the heart rate variability (HRV) of healthy person from Electrocardiogram (ECG) signal. Some non-linear techniques are applied to different raw data (RR intervals of ECG) that are derived from the sample ECG records from MIT-BIH database. Electrocardiogram (ECG) signal gives significant information for the cardiologist to detect cardiac diseases. ECG signal is a self-similar object. So, fractal analysis can be implemented for proper utilization of the gathered information. A technique of nonlinear analysis- the fractal analysis is recently having its popularity to many researchers working on. In general, fractals can be any type of infinitely scaled and repeated pattern. A fractal is a natural phenomenon or a mathematical set that exhibits a repeating pattern that displays at every scale due to the self-similarity in the Heart’s electrical conduction mechanism and self-affine behaviour of Heart Rate (HR). It is also known as expanding symmetry or evolving symmetry. Fractal analysis is measures complexity using the fractal dimension. Self-similarity dimension is one of the classifications of Fractal Dimension (FD). If the replication is exactly the same at every scale, it is called a self-similar pattern. So, fractal analysis can be implemented for proper utilization of the gathered information. It is expected that the proposed technique will provide a better result by comparison will others to calculate FD of ECG signal.
