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.

Indian Pacing and Electrophysiology Journal, 2002 Vasovagal syncope is a common condition, usually associated with a benign prognosis. Most sufferers experience only occasional symptoms, and can be treated with reassurance and lifestyle advice. However, a minority of patients are debilitated by frequent

Síncope reflexa vasovagal – haverá benefício da terapêutica com pacemaker?
Revista Portuguesa de Cardiologia, 2014 Resumo: A síncope reflexa vasovagal afeta frequentemente uma população jovem estando associada a um prognóstico benigno em termos de mortalidade. No entanto, uma minoria de doentes apresenta episódios recorrentes com grande repercussão na sua qualidade ...

Ultrasonography-guided central venous catheterisation in haematological patients with severe thrombocytopenia [PDF]
, 2013 BACKGROUND: Cannulation of the internal jugular vein (CVC) is a blind surface landmark-guided technique that could be potentially dangerous in patients with very low platelet counts.

Spectral analysis of heart rate variability for assessment of autonomic nervous system activity during head-up tilt table testing [PDF]
, 2014 Spectral analysis of heart rate variability was used to assess changes in activity of autonomic nervous system (ANS) in 84 patients with history of recurrent syncope and 21 normal controls.

Experimental Physiology, EarlyView.Abstract Orthostatic stress reduces venous return and stroke volume (SV), risking cerebral hypoperfusion despite autonomic compensation. Although lower‐limb counterpressure manoeuvres improve cerebral perfusion in upright posture, their effects on cerebral blood velocity (CBV) during lower‐body negative pressure (LBNP) and the associated mechanisms are

The Journal of Physiology, EarlyView.Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.
