Nikhil Pachauri, Dipak Kumar Mishra . Phase Synchronization and Coherence Analysis between ECG & Arterial Blood Pressure. International Journal of Computer Applications. 44, 18 ( April 2012), 27-30. DOI=10.5120/6364-8701
Abstract
Phase synchronization is an important phenomenon of nonlinear dynamics and has recently received much scientific attention. Phase synchronization is a type of synchronization reflecting mutual adjustment of rhythms of self-sustained oscillatory systems. Time-varying phase synchrony is an important bivariate measure that quantifies the dynamics between non-stationary signals and has been widely used in many applications including chaotic oscillators in physics and multichannel electroencephalography recordings in neuroscience. In this paper we investigate that phase synchronization between electrocardiogram and arterial blood pressure was used in order to find the interaction between these two signals. With the help of coherence phase we are able to tell which signal is lagging and which signal is leading.
