Assessment of Autonomic Function in Subjects Practicing Yoga Using Spectral Analysis and Approximate Entropy Method
Autonomic nervous system involvement in subjects practicing Yoga has rarely been studied and has shown conflicting results. Our main purpose was to assess the effect of Yoga on autonomic function of group of subjects practicing Yoga regularly in comparison with another group with normal control subjects by measuring the frequency gain response of the two groups. Other aim of this study was to determine wither the duration of Yoga practicing correlated with measures of heart rate variability signal (HRV) using approximate entropy index (ApEn).
Hemodynamic and Autonomic Reactivity to Mental and Physical Stress in Lean, Overweight and Obese Subjects
There could be progressive changes in hemodynamic and autonomic parameters causing cardiovascular damage from lean to morbid obesity. We aim to study resting and reactivity of hemodynamic and autonomic parameters to physical and mental stress in lean, overweight and obese subjects of the Oman Family Study (OFS).
Could Non-Linear Heart Rate Variability Analysis of Short RR Intervals Series Give Clinically Valuable Information in Heart Disease?
New analytic methods based on nonlinear system theory have been developed to characterize the nonlinear features in HR dynamics. It is known from long time series (24h ECG recordings) that patients with chronic heart failure or stable coronary heart disease have altered fractal organization in heartbeat dynamics. During such long-time series, many confounding could limit the assessment of autonomic functions.
Statistics across industrialised societies show that occupational stress results in social and financial costs for individuals, organisations, and economies. Occupational stress is prevalent in many different forms, for example, work intensification, dissatisfaction with current work schedules, feelings of job insecurity, more work being done at odd hours, the spread of new information and communication technologies, and long hours becoming more common.
