Sažetak
The multifractal aproach has been applied to temporal fluctuations of heartbeat (RR) intervals, measured in various regimes of physical activity (ergomeric data), taken from healthy subjects and that of having stable angina pectoris (SAP). The problem we address here is whether SAP changes multifractality observed at healthy subjects. The G-moment method is used to analyze the multifractal spectrum. It is observed that both sets of data characterize multifractality, %No significant difference between the multifractal spectra of healthy subject %and SAP has been found. but different trend in multifractal behaviour is found for SAP desease, under pronounced physical activity.
