Tilt Training Increases Vasoconstrictor Reserve in Patients with Neurocardiogenic Syncope [PDF]

, 2012
A síncope neurocardiogénica (SNc) é uma entidade clínica comum, resultante de uma resposta autonómica reflexa excessiva durante o stress ortostático. As diferentes opções terapêuticas são controversas e de eficácia limitada.

Haemochromatosis ‐ a modern clinician’s guide

Internal Medicine Journal, EarlyView.
Abstract Haemochromatosis is an inherited disorder of iron metabolism affecting approximately 100 000 Australians. Iron overload may result in end organ dysfunction, most commonly manifesting as chronic liver disease, arthropathy and endocrinopathies. End organ complications can be prevented, minimised or reversed, with early diagnosis and initiation ...

Hemodynamic measurements for evaluating vasovagal syncope in the emergency department [PDF]

Clinical and Experimental Emergency Medicine, 2015
Syncope is a sudden and transient loss of consciousness and postural tone, with spontaneous recovery without medical intervention. It accounts for 1.0% to 1.5% of emergency department (ED) visits and up to 6% of hospital admissions. Vasovagal syncope may

Autonomic Nerve Activity and Blood Pressure in Ambulatory Dogs [PDF]

, 2014
Background The relationship between cardiac autonomic nerve activity and blood pressure (BP) changes in ambulatory dogs is unclear. Objective To test the hypotheses that simultaneous termination of stellate ganglion nerve activity (SGNA) and vagal ...

PFA Under Deep Sedation and Non‐Invasive Monitoring in Atrial Fibrillation Patients With Obstructive Sleep Apnea

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Clinical data about pulsed field ablation (PFA) under deep sedation among patients with obstructive sleep apnea (OSA) are limited, while the optimal periprocedural monitoring is not established. We report our experience in PFA among patients with atrial fibrillation (AF) and OSA, using a continuous non‐invasive respiratory and ...

Vascular health and exercise in females throughout the lifespan: Exploring puberty, pregnancy and menopause

Experimental Physiology, EarlyView.
Abstract This narrative review highlights the impact of exercise on vascular health in females over the lifespan with an emphasis on puberty, pregnancy and menopause. These events encompass substantial changes in sex hormone levels, particularly oestrogens and progesterone.

Machine Learning Model Using Heart Rate Variability for the Prediction of Vasovagal Syncope

IEEE Access
Vasovagal syncope is a reversible condition that can cause serious events, such as cerebral hemorrhage. Predicting its occurrence is challenging; thus, this study aimed to develop machine learning models that use heart rate variability to predict the ...

Structural heart disease as the cause of syncope

Brazilian Journal of Medical and Biological Research, 2018
We described the clinical evolution of patients with structural heart disease presenting at the emergency room with syncope. Patients were stratified according to their syncope etiology and available scores for syncope prognostication.

Genetics of vasovagal syncope [PDF]

Autonomic Neuroscience, 2014
Vasovagal syncope (VVS) is the most frequent type of syncope and affects about 25% of the population. The role of genetic factors in VVS has long been debated. In this review we will discuss the current evidence that strongly suggests a major genetic component.Family aggregation studies have consistently shown that individuals with VVS more frequently ...
