In general, the initial “treatment” of all forms of neurally-mediated reflex syncope comprises reassurance as to the benign nature of the syndrome, education regarding avoidance of triggering events and predisposing factors, recognition of premonitory symptoms and manoeuvres to abort the episode, the avoidance of volume depletion and prolonged upright posture. The above measures are sufficient ...

OBJECTIVE To evaluate the effect of sublingual administration of ISDN on the results of the head-up tilt table test (HUTT) in children and adolescents with vasovagal syncope. MATERIALS AND METHODS The study group consisted of 30 children, each with at least one incidence of vasovagal syncope, and the control group had 15 healthy children. The patients were tilted upright at an angle of 60° fo...

OBJECTIVE To investigate the peripheral venous response to head up tilting in malignant vasovagal syndrome. PATIENTS 31 Patients with unexplained syncope or dizziness referred from the cardiology department. METHODS Changes in calf venous volume were studied by a radionuclide technique during 45 degrees head up tilt testing. RESULTS During tilt testing six patients became syncopal but 25 ...

Blood pressure and heart rate are controlled by complex interactions between different reflexes, including input from low-pressure cardiopulmonary receptors and high-pressure baroreceptors that are within the aortic arch and carotid sinus. Although the exact mechanisms leading to neurocardiogenic (vasovagal) syncope remain somewhat unclear, during central volume unloading the inactivation of hi...

In the pathophysiological study of vasovagal syncope, the nature of the interaction between baroreceptor sensitivity (BS), sympathetic withdrawal, and parasympathetic activity has yet to be ascertained. Altered BS may predispose toward abnormal sympathetic and parasympathetic responses to orthostasis, causing hypotension that may progress to syncope if there is sympathetic withdrawal. To examin...

introduction: medical emergencies can frequently happen in dental settings and inability to cope with them can lead to tragic outcomes. the of aim of this study was to evaluate the occurrence of medical emergencies in dental settings in babol, iran and dentists’ self-perceived need for practical training in this field. materials and methods: a descriptive-ana-lytical study was performed by usin...
