Dreaming experience as a useful diagnostic clue for syncopal episodes.
BACKGROUND The differential diagnosis between epileptic seizures and syncopes is a common occurrence in clinical practice. The manifestations of seizure and syncope sometimes overlap, and available diagnostic testing often not provides a conclusive answer. Syncope is often preceded by a symptom complex characterized by lightheadedness, generalized muscle weakness, giddiness, visual blurring, ti...
متن کاملUnusual cause of syncopal episodes
We report a 43-year-old man who had been experiencing recurrent attacks of syncope for several years, and a search for the causes behind these lapses in consciousness was fruitless for many years. The patient was admitted to our department of internal medicine because of the symptoms flushing, hypotension and episodes of syncope. After a careful anamnesis and then a comprehensive investigation,...
متن کاملLow-frequency oscillation of sympathetic nerve activity decreases during development of tilt-induced syncope preceding sympathetic withdrawal and bradycardia.
Sympathetic activation during orthostatic stress is accompanied by a marked increase in low-frequency (LF, approximately 0.1-Hz) oscillation of sympathetic nerve activity (SNA) when arterial pressure (AP) is well maintained. However, LF oscillation of SNA during development of orthostatic neurally mediated syncope remains unknown. Ten healthy subjects who developed head-up tilt (HUT)-induced sy...
متن کاملTestosterone and sympathetic nerve activity during pregnancy.
1 that examined the influence of testosterone on the endothelial nitric oxide (NO) system. The role of testosterone in gestational car-diovascular function has not been adequately examined, despite the fact that testosterone levels are exaggerated in preeclamptic and polycystic ovary syndrome pregnancies. Chinnathambi et al 1 used a well-controlled experimental model in which pregnant rats were...
متن کاملAnthropometric characteristics and tilt table test results.
We appreciate the interest of Dr H. J. Koch et al. in our article and the opportunity to respond. As they state, sports medicine has become more involved in syncope and in the tilt table test. The sports medicine literature recognizes the term exerciseassociated collapse (EAC) to describe athletes who are unable to stand or walk unaided as a result of lightheadedness, feeling faint, dizziness o...
