13. Autonomic dysfunction is common in liver cirrhosis and is associated with cardiac dysfunction and mortality: prospective observational study
ABSTRACT BACKGROUND: Although autonomic dysfunction has been shown to be associated with liver cirrhosis, the prevalence and prognostic implications are unclear. Abnormal heart rate variability (HRV), a measure of autonomic function, has not been well investigated in cirrhosis. OBJECTIVE: To evaluate the prevalence of high-risk HRV parameters in a cohort o

14. DOES GREEN TEA ENHANCE THE EFFECTS OF PHYSICAL TRAINING ON HEART RATE VARIABILITY?
RESUMO Introdução: O chá verde está associado a uma série de benefícios à saúde, assim como o treinamento físico. Porém, a associação de ambos apresenta efeitos cronotrópicos e autonômicos cardíacos pouco conhecidos. Objetivo: Avaliar o efeito da associação da administração crônica de chá verde e do treinamento físico sobre a frequên

15. Linear and Nonlinear Heart Rate Variability Analysis in Gonadal Dysgenesis (Swyer Syndrome): A Case Report
Abstract Swyer syndrome is one of the disorders of sexual differentiation. Previous studies have demonstrated increased sympathetic activity with heart rate variability (HRV) analysis with decreasing estradiol levels. One patient presented a pure 46, XY gonadal dysgenesis with female phenotype. Cardiac autonomic modulation was assessed through HRV analysis w

16. Cardiovascular Physiotherapy on Respiratory Sinus Arrhythmia of Patients Undergoing Coronary Artery Bypass Grafting
Abstract Introduction: Patients in the postoperative period of coronary artery bypass grafting (CABG) present respiratory and autonomic dysfunctions. In this sense, cardiovascular physiotherapy has been offered as an indispensable differential for the improvement of the prognosis of this population. Heart rate variability is a simple, noninvasive method to

17. Home-Based Resistance Training in Heart Diseases: Don't Stop the Music, your Muscles are still Listening
Abstract Background: Nasal mucociliary clearance (NMC) responds to autonomic activity through exercise. However, there is a gap in the literature on how NMC responds to resistance exercise. Objective: To evaluate the acute effects of resistance tube exercise on NMC and the autonomic nervous system in smokers. Methods: Clinical trial was performed with 18

20. Cardiac Autonomic Modulation of Healthy Individuals and Patients with Chronic Obstructive Pulmonary Disease During Spontaneous and Controlled Breathing
Abstract Background: Lung diseases and different forms of breathing may interfere with cardiac autonomic modulation (CAM). Objective: To compare CAM in individuals with chronic obstructive pulmonary disease (COPD) with healthy individuals during spontaneous breathing (SB) and controlled breathing (CB). Methods: Cross-sectional study involving 30 individua

21. DOES HABITUAL PHYSICAL ACTIVITY LEVEL INFLUENCE AEROBIC CAPACITY AND HEART RATE VARIABILITY IN POSTMENOPAUSAL WOMEN?
RESUMO O objetivo da pesquisa foi verificar se o nível de atividade física habitual (NAFH) de mulheres em fase pós menopausa apresenta influência na capacidade aeróbia e atividade parassimpática em repouso. Participaram do estudo 30 mulheres na fase da pós menopausa (59,3 ± 5,3 anos; 1,58 ± 0,06 m; 64,5 ± 9,6 kg; 25,6 ± 3,1; %G = 27 ± 5%). Foram

23. Empathy and autonomic and hemodynamic cardiac responses
Resumo Respostas hemodinâmicas e autonômicas têm sido utilizadas como indicadores sensíveis da saúde cardiovascular durante situações de cunho emocional. Todavia, ainda são escassos os trabalhos que avaliam esses indicadores quando os sentimentos produzidos ocorrem a partir de experiências vicárias. O presente estudo objetivou verificar se medidas

24. The Psychophysiological Responses of the Chronic Ischemic Stroke Patients to the Acute Stress were Changed
Abstract: Mood disorder is one of the complications of stroke. The inability to cope with stress is also a prognosis of depression and anxiety. The aim of this study is to assess the response of stress system in the post stroke patients. Twelve healthy controls (HC) and twelve post-stroke patients after filling in the State-Trait Anxiety Inventory completed
