Multifractal analysis of Electronical Cardiogram taken from healthy subjects

摘要

ECG (Electronical Cardiogram) data taken from healthy adult subjects is found characterizing multifractality. We find that the radius of the curvature of the young's multifractal spectrum is greater than the old ones. We further find that the area of young adult subject's multifractal spectrum is far larger than the older one's and the logarithm of the area of the spectrum is inverse proportion to age. It shows that when time is running on human heartbeat energy is exponentially decreasing until heart failure.
