Patterns of cardiorespiratory coordination in young women with recurrent major depressive disorder treated with escitalopram or venlafaxine

Altered cardiorespiratory coupling in young male adults with excessive online gaming

“…Additionally, our study provides the first demonstration of the inverse relationship between autonomic complexity and severity of PIU. High cross-SampEn values indicate overall operative ranges of central autonomic regulation (Chang et al, 2012). Our results therefore suggest that reduced autonomic complexity is a marker of the PIU state.…”

“…Because the network interaction between heart rate and respiration is mainly governed by central autonomic modulation (Berger et al, 2010), reduced CRC appears to reflect alterations in efferent output from the CAN. Taken together, these findings suggest that male individuals with excessive online gaming may have altered central autonomic control over autonomic responses to pleasurable computer gaming, thereby triggering uncontrollably prolonged gaming and socio-occupational difficulties (Chang et al, 2012;Peupelmann et al, 2009;Shapira et al, 2000).…”

“…When the association between RR intervals and interbreath intervals is strong, the cross-SampEn value may decrease. In contrast, when there is a weak association between the two time series datasets, the cross-SampEn values are larger, indicating relatively low synchrony (Chang et al, 2012).…”

“…The CRC measures quantify the strength of the association between the two physiological systems (i.e., the cardiac and respiratory systems) under the central autonomic control (Dick and Morris, 2004), and thus the resting level of CRC is largely associated with overall output of central autonomic network (CAN) (Peupelmann et al, 2009). In a recent study on the relationship between pharmacodynamics properties and CRC level, the changes in the CRC level was closely associated with the dose of central norepinephrine enhancer (Chang et al, 2012). By combining HRV with the respiratory rhythm, CRC can enhance the signal-to-noise ratio and be used to evaluate the intrinsic interactions among higher regulatory centers (Lalley, 2008;Peupelmann et al, 2009).…”

Effects of antipsychotic drugs on cardiovascular variability in participants with bipolar disorder

“…Small samples and variability in the classification of exposure may explain these conflicting conclusions. Some inconsistencies between previous studies could also be due to differences in the extent of psychiatric disease progression or differences in the pharmacodynamics of the studied agents (Bar et al , 2007; Bar et al , 2008b; Chang et al , 2012b; Chang et al , 2012a). …”
