Complex dynamics of the biological rhythms: gallbladder and heart cases

Abstract: A theoretical analysis of the mechanisms underlying the dynamics of gallbladder and heart pulsation could clarify the question regarding the classification as chaotic of the associated behaviour, eventually related to a normal and healthy beat; this analysis is particularly relevant in view of the control of dynamic bifurcations arising in situations of disease. In this work a summary of the DFA method applied to gallbladder volume data for a modest number of healthy and ill patients is presented: the presence of signal correlation is found in both cases, but the fit shapes differ from some critical values.
