Effect of gastric myoelectric activity on pulse rate variability in fasting and postprandial conditions

摘要

Aim of this paper is to study the effect of Gastric Myoelectric Activity (GMA) in finger PPG signal. To this end, Pulse Rate Variability (PRV) analysis in combination with Poincare plots was selected. In PRV, the power of High Frequency (HF) component significantly changes in fasting and postprandial state and positively correlated between Power Ratio (PR) of PRV and electrogastrography (EGG) power (r = 0.46; P < 0.05). The results of this study explored that the combination of Poincare plots and PR value could show a new insight into the assessment of gastrointestinal system between different body conditions of a healthy group.
