Low heart rate variability is a sign of stress while a high heart rate variability suggests a relaxed and healthy state.
VivoSense HRV analysis module was used to analyze the PPG signal from a pulse oximeter, identifying the peaks, managing the artifact and calculating the desired HRV measures. The paper can be found at http://archpsyc.jamanetwork.com/article.aspx?articleid=2436276 with details of how VivoSense was used in the methods supplement.
