Remote work is a novel job condition characterized by an overlap between working and domestic demands. The stress-related impact of this modality has been mainly evaluated qualitatively but not quantitatively. The aim of the study was to compare the cardiac autonomic profile of office employees with and without children during a day of remote work by means of power spectral analysis of heart rate variability extracted by a 24-hour Holter ECG recording. A visual analogue scale (VAS) was collected to measure the rate of the perceived level of stress while remotely working. Fifty subjects were enrolled: 23 with at least one child (CHILD group, 9 males) and 27 without (NO_CHILD group, 16 males). Vagal modulation was assessed as the power of the RR interval time series in the high frequency (HFRR, from 0.15 to 0.40 Hz) band. The VAS was not significantly different in the two groups. HFRR did not exhibit circadian rhythm in CHILD group, while it was higher during NIGHT compared to DAY in NO_CHILD group. During NIGHT, HFRR was greater in NO_CHILD than in CHILD group. During remote working, CHILD group was characterized by a reduced nocturnal vagal modulation compared to NO_CHILD one. The latter result might be considered a risk factor for cardiovascular disease in the long-term period.

The photo-plethysmography (PPG) is a measuring method allowing for approachable analysis of heart rate. We have made an attempt of heart rate asymmetry (HRA) assessment from a PPG signal. 413 cardiac trace recordings of healthy young people obtained from an open database have been analyzed. We have used standard HRA descriptors and also evaluated the mean deceleration input (DI) into heart rate transitions to assess HRA in PPG. We have observed asymmetry in the majority of studied subjects (DI < 0.5 in 63.4 % of participants). The investigation of temporal variability in heart rate obtained with analysis of three consecutive heartbeat intervals is a valuable tool that may be helpful in the evaluation of autonomic nervous system performance.

In this study, the response of skin blood flow to lo-cal heating of subject's forearm was assessed by imaging photo-plethysmography. The proposed system is featured by accurate control of the parameters affecting the endothelium during pro-longed measurements. It is shown that this method reliably re-flects the function of the mechanisms of regulation of peripheral vascular resistance, which is of great prognostic value for the de-tection of cardiovascular diseases.

Recent studies showed that the information coming from the heart is constantly processed by the brain. One index to study this process is the heartbeat-evoked potential (HEP), represented by an event-related potential component related to the cortical processing of the heartbeat. In this study we propose an approach to investigate the heartbeat-evoked EEG responses, based on quantifying the changes induced by the heartbeat on the predictability of the brain dynamics. The regularity of EEG signals is assessed through the Information Storage (IS) computed with a time-varying approach able to derive the temporal profile of the measure for each time point. Results show a modulation in the regularity of EEG signals induced by the heartbeat that can be revealed with the proposed approach in a group of healthy subjects during a resting state.

Some aspects of cardiorespiratory coupling (CRC) require tools capable of accounting for nonlinearities. Joint symbolic analysis (JSA) has been proposed to characterize CRC via the rate of short, jointly coordinated (C), patterns obtained from the heart period (HP) variability and respiration (R) series. C schemes were distinguished according to the dominant time scale governing CRC. We applied JSA to a database of 19 healthy subjects (age: 27–35 yrs, median = 31 yrs; 8 males) during spontaneous and paced breathing at varying respiratory rates. The rate of C pattern did not vary with the breathing rate, but the proportions of C pattern families changed with respiratory frequency. We conclude that JSA is a useful tool to investigate the effect of breathing patterns on CRC, with potential applications in patients with respiratory failure such as that developed in COVID-19 syndrome.

Parkinson disease affects not only motor control system but it is often accompanied by non-motor symptoms, including signs of autonomic control impairment. The study was aimed to detect cardiovascular control impairment in the early stage of Parkinson disease employing wide array of measures characterizing parasympathetic and sympathetic control of heart and vessels and their response to orthostatic and cognitive load. We found only subtle alterations in sympathetic control of heart (inotropy) and vessels (vascular response to orthostasis) pointing towards a dominance of motor symptoms in the early stage of Parkinson disease.

Oscillations in cardiovascular variables may be part of the cardiovascular control mechanisms. Heart rate variability in the high frequency interval is part of the cardiorespiratory interactions. Main part of high frequency heart rate variability is called respiratory sinus arrhythmia, which is influenced by ventilation pattern. We investigated how addition of 5 % CO2 to the air affected the high frequency heart rate variability. CO2 breathing increased heart rate variability, and this was linearly related to increases in both tidal volume and end-tidal CO2. CO2 breathing also increased heart rate, which did not affect heart rate variability.

Using 5-minute resting beat-to-beat recordings of systolic blood pressure and RR intervals from ECG from 169 healthy young adults, we present a novel method of estimating various features of the spontaneous baroreflex function, i.e., the ppBR method. These features include short- and long-term, and total baroreflex sensitivity and baroreflex effectiveness. This method also demonstrates that spontaneous baroreflex is asymmetrical only for recordings with the preserved, original order of systolic blood pressure and RR intervals. If this order is randomly shuffled to remove the physiological associations, all asymmetrical features of baroreflex sensitivity and baroreflex effectiveness are abolished.

Arterial compliance is an important parameter influencing ventricular-arterial coupling, depending on structural and functional mechanics of arteries. In this study, the spontaneous beat-to-beat variability of arterial compliance was investigated in time and frequency domains in thirty-nine young and healthy subjects monitored in the supine resting state and during head-up tilt. Spectral decomposition was applied to retrieve the spectral content of the time series associated to low (LF) and high frequency (HF) oscillatory components. Our results highlight: (i) a decrease of arterial compliance with tilt, in agreement with previous studies; (ii) an increase of the LF power content concurrent with a decrease of the HF power, potentially reflecting changes in vasomotor tone, blood pressure and heart rate variability associated with higher sympathetic activity and vagal withdrawal occurring with tilt.

In this work, nonlinear model-free methods for bivariate time series analysis have been applied to study cardiorespiratory interactions. Specifically, entropy-based (i.e. Transfer Entropy and Cross Entropy) and Convergent Cross Mapping asymmetric coupling measures have been computed on heart rate and breathing time series extracted from electrocardiographic (ECG) and respiratory signals acquired on 19 young healthy subjects during an experimental protocol including spontaneous and controlled breathing conditions. Results evidence a bidirectional nature of cardiorespiratory interactions, and highlight clear similarities and differences among the three considered measures.
