Neurally mediated syncope.
Neurally mediated syncope is a disorder of the autonomic regulation of postural tone, which results in hypotension, bradycardia, and loss of consciousness. A wide variety of stimuli can trigger this reflex, the most common stimulus being orthostatic stress. Typically, a patient with neurally mediated syncope experiences nausea, lightheadedness, a feeling of warmth, and pallor before abruptly lo...
متن کاملPharmacotherapy of neurally mediated syncope.
A wide variety of pharmacological agents are currently used for prevention of recurrent neurally mediated syncope, especially the vasovagal faint. None, however, have unequivocally proven long-term effectiveness based on adequate randomized clinical trials. At the present time, beta-adrenergic receptor blockade, along with agents that increase central volume (eg, fludrocortisone, electrolyte-co...
متن کاملSpectral Analysis of Heart Rate Variability in Neurally Mediated Syncope Compared to Healthy Subjects
Correspondence to: Victor Moga, MD, PhD Clinic of Cardiology, Timiooara County Hospital, 10 Iosif Bulbuca St., 300736 SUMMARY: Heart rate variability (HRV) represents the widely used method for the assessment of the autonomic tone. Time domain parameters, like standard deviation of all RR intervals and spectral analysis, expressed as the spectral power density (PSD) in both low frequency (LF: 0...
متن کاملNeurally-mediated syncope: an overview and approach.
The Bezold-Jarisch reflex has been incriminated for the vasodepressor and cardioinhibitory response seen in vasovagal syncope. By animal studies it has been shown that venous pooling leading to decrease in the end-diastolic volume and increase in ventricular inotropy. This leads to stimulation of the stretch receptors in the inferoposterior wall of the ventricular and increased afferent signals...
متن کاملInduction of neurally mediated syncope with adenosine.
BACKGROUND Tilt testing is used to establish the diagnosis of neurally mediated syncope. However, applicability of the tilt test is limited by test sensitivity and length of time required to perform the test. We hypothesized that adenosine could facilitate the induction of neurally mediated syncope through its sympathomimetic effects and therefore could be used as an alternative to routine tilt...
