Special Issue Information

Dear Colleagues,

Entropy is a nonlinear measure employed to quantify the dynamical properties of biomedical signals. Various methods based on Shannon entropy have been applied to estimate the complexity or irregularity of multivariate signals over multiple scales; these have also been utilized in the analysis of cardiac and respiratory time series to examine the features of bidirectional cardiorespiratory interactions. In the last few decades, in addition to the neural control of the heart rhythm, many basic and clinical studies have revealed the properties of the neural control of breathing. However, we remain unable to recognize the whole spectrum of the variability in cardiorespiratory coupling during wakefulness, sleep, exercise or changes in the cardiovascular and respiratory system induced by pathological conditions. This Special Issue aims to disseminate the results obtained via the development of novel entropy metrics and/or the implementation of standard entropy measures under the different physiological and pathological conditions applicable in the examination of cardiorespiratory interactions.

Individuals with gaming disorder (GD) show emotional dysregulation and autonomic dysfunction in daily life. Although studies have shown that the relaxation method of breathing exercise (BE) improves cardiopulmonary synchrony, the physiological regularity and synchrony of GD remain unclear. In this study, we investigated the regularities of pulse wave (PW), thoracic wall movement (TWM), and abdominal wall movement (AWM) using sample entropy (SE) and assessed the vascular-respiratory and TWM-AWM synchrony using cross-sample entropy (CSE). Twenty individuals with GD and 26 healthy control (HC) individuals participated in baseline, gaming, and recovery stages, both before and after BEs. The results showed that both groups had significantly higher SETWM, SEAWM, and CSETWM-AWM during gaming than baseline. Before BE, CSEPW-TWM and CSEPW-AWM during gaming were considerably higher in the GD group than in the HC group. Compared to before BE, both groups had decreased SETWM and CSETWM-AWM during gaming, particularly in the HC group. Online gaming may induce pulse wave and respiratory irregularities, as well as thoracic–abdominal wall movement asynchrony. Individuals with GD who engage in prolonged gaming periods may exhibit lower vascular–respiratory synchrony compared to the HC group. SETWM, SEAWM, CSETWM-AWM, CSEPW-TWM, and CSEPW-AWM may serve as biomarkers for assessing the risk of GD. BE may improve TWM regularity and vascular–respiratory synchrony during gaming, potentially alleviating addictive behavior. Full article
