Indices of cardiorespiratory synchronization from rat blood pressure data
A recently developed method for the detection of phase synchronization between several oscillatory processes from one-dimensional signals has been extended to allow estimation of synchronization indices. It has been applied to blood pressure signals from freely moving rats. Each rat underwent four stages: 1) healthy; 2) healthy but challenged by beta-blockers; 3) with stress-induced myocardial injuries; 4) with the stress-induced injuries challenged by beta-blockers. It is shown that cardiorespiratory synchronization plays аn essential role at each оf these stages.
