1. Dysautonomic Arrhythmogenesis: A Working Hypothesis in Chronic Chagas Cardiomyopathy
Abstract Sudden cardiac arrest (SCA) represents the most dramatic course of chronic Chagas cardiomyopathy (CCC) and is closely related to the presence of ventricular arrhythmias and heart disease. Although several aspects of ventricular arrhythmias in CCC have been elucidated in the last decades, such as the role of impaired cardiac autonomic modulation repo

2. Evaluation of the Autonomic Nervous System in Chronic Chagasic Cardiopathy: A Systematic Review of the Literature
Abstract Background The importance of regional sympathetic denervation in the pathophysiology and prognosis of Chagas disease has been recognized. Objective To conduct a review of studies that have assessed dysautonomia in chronic Chagas heart disease. Methods The search was performed on the Medline, Pubmed, Lilacs and SciELO databases. The inclusion c

3. Vitamin D, vitamin D binding protein, vitamin D receptor levels and cardiac dysautonomia in patients with multiple sclerosis: a cross-sectional study
RESUMO A vitamina D é um hormônio esteroide pleiotrópico que modula o equilíbrio autonômico. Sua deficiência tem sido descrita como fator de risco ambiental para esclerose múltipla (EM). O objetivo deste estudo foi investigar os níveis séricos de vitamina D, proteína de ligação à vitamina D (VDBP) e receptor de vitamina D (VDR) e avaliar a disau

5. Effects of Brazilian scorpion venoms on the central nervous system
Abstract In Brazil, the scorpion species responsible for most severe incidents belong to the Tityus genus and, among this group, T. serrulatus, T. bahiensis, T. stigmurus and T. obscurus are the most dangerous ones. Other species such as T. metuendus, T. silvestres, T. brazilae, T. confluens, T. costatus, T. fasciolatus and T. neglectus are also found in the

6. Recurrence Plots: a New Tool for Quantification of Cardiac Autonomic Nervous System Recovery after Transplant
Abstract Objective: To evaluate a possible evolutionary post-heart transplant return of autonomic function using quantitative and qualitative information from recurrence plots. Methods: Using electrocardiography, 102 RR tachograms of 45 patients (64.4% male) who underwent heart transplantation and that were available in the database were analyzed at differ

7. Neural mechanismsand post-exercise hypotension: The importance of experimental studies
Abstract A single bout of exercise can decrease blood pressure level in hypertensive individuals and this phenomenon is known as post-exercise hypotension (PEH). PEH is clinically important and reduces blood pressure after physical exercise in hypertensive subjects. This reduction has been attributed to autonomic mechanisms, e.g., reduced peripheral sympathe

8. Heart rate variability as important approach for assessment autonomic modulation
Abstract Alterations in the heart rate recovery and heart rate variability have been associated with greater risk of mortality and early prognosis of cardiac diseases. Thus, strategies for assessing autonomic nervous system and its modulation to the heart are crucial for preventing cardiovascular events in healthy subjects as well as in cardiac patients. In

9. Behaviour, heart rate, and heart rate variability in pigs exposed to novelty
ABSTRACT In the present study, we investigated behavioural responses and determined parameters of heart rate variability (HRV) to elucidate a relative activation of autonomic nervous system (ANS) during baseline (10 min) and in response to potentially stressful situations (10 min) in two pig breeds and sexes. Gilts (n = 21) and barrows (n = 9) of the Landrac

10. Non-linear indices of heart rate variability during endodontic treatment
Abstract Dental treatment promotes psychosomatic change that can influence the procedure and compromise the general well-being of the patient. In this context, it highlights the importance of evaluating the function of the autonomic nervous system in individuals undergoing endodontic treatment. Thus, this manuscript aimed to analyse cardiac autonomic modulat

11. Heart rate turbulence analysis in female patients with fibromyalgia
OBJECTIVE: Fibromyalgia is characterized by diffuse musculoskeletal pain and discomfort. There are several reports regarding autonomic nervous system dysfunction in patients with fibromyalgia. Heart rate turbulence is expressed as ventriculophasic sinus arrhythmia and has been considered to reflect cardiac autonomic activity. Heart rate turbulence has been

12. Influence of resistance training on cardiac autonomic modulation: literature review
RESUMO Entre os benefícios promovidos pelo treinamento resistido, a sua influência sobre a modulação autonômica cardíaca nos chama a atenção, tendo em vista a importância do sistema nervoso autônomo (SNA) no controle das funções internas do organismo. O objetivo da presente revisão narrativa foi reunir informações a respeito dos efeitos do tr
