Vasovagal syncope (VVS) is known to have a benign prognosis and be associated with enhanced contraction and activation of the left ventricular (LV) mechanoreceptors. However, a little is known about VVS in patients with LV dysfunction. The present study aimed to investigate the prevalence and ...
Objective: In this study, we aimed to evaluate 3-year mid-term follow-up results that consist of treatment response, frequency of recurrences, predisposing factors effective on recurrence and prognosis in patients with syncope and presyncope. We also aimed to obtain useful information that will con...
Malignant vasovagal syncope (VVS) is a unique form of cardioinhibitory VVS, characterized by prolonged asystole. To deepen the understanding of this distinct type of VVS in children, this article reviews advancements in the potential pathogenesis, diagnostic approaches, clinical significance, and treatmen...
For both non-baroreflex and baroreflex responses, there were no differences in any of the MSNA indices between the syncope groups. Patients with vasovagal syncope, with or without sleep syncope, have very similar sympatho-vagal responses to both non-baroreflex and baroreflex stimuli. This is ...

Pulse wave analysis (PWA) is widely used to evaluate vascular properties, as it reflects the condition of the ...
syncope. Patients with heart and brain diseases were excluded. Based on the result of passive HUTT (positive vs. negative) the study group was divided into two separated sub-groups signified respectively as HUTT(+) and HUTT(−). The HUTT(+) sub-group consisted of 57 patients who ...
Vasovagal syncope is a common symptom, but its true incidence is difficult to estimate because only a small percentage of patients with syncope seek medical advice. The estimated prevalence varies according to the setting and the population studied, but it is likely that up to 40 % of people ...
Tilt testing for the investigation of the clinical problem of syncope was introduced in the mid 1980s [1,2]. It represented an advance in the approach to this clinical arena, which had always offered serious challenges to physicians, because it became possible to reproduce the patient’s sympto...
