Blog Article

Abstract: Abstract: The cardiac dynamics during meditation is explored quantitatively with two chaos-based non-linear techniques viz.multi-fractal detrended fluctuation analysis and visibility network analysis techniques.The data used are the instantaneous heart rate (in beats/minute) of subjects performing Kundalini Yoga and Chi meditation from read more PhysioNet.The results show consistent differences between the quantitative parameters obtained by both the analysis techniques.This indicates an interesting phenomenon of change in the complexity of the cardiac dynamics during meditation supported with quantitative parameters.

The results also produce a preliminary evidence that these techniques can be used as a measure of physiological here impact on subjects performing meditation.
