Multifractal Correlation Study Between Posture and Autonomic Deregulation Using ECG and Blood Pressure Data



Recently posture-induced cardiovascular changes have become a subject of study for its obvious implications. This chapter presents analysis of non-linear time series of ECG and arterial blood pressure (ABP) data from a new perspective using state-of-the-art non-linear technique for assessment of cardiac disorder induced by different human posture. Precisely two methods multifractal detrended fluctuation analysis and multifractal detrended cross-correlation analysis have been applied to ECG and ABP data to quantify degree of impact of posture on cardiovascular functions. Moreover the knowledge of cross-correlation parameters is significant as it provides information for understanding the dynamics of orthostatic stress.
