Vasovagal syncope (VVS) is a common clinical problem characterized by transient episodes of loss of consciousness due to abnormal autonomic activity. This paper describes two groups of monozygotic twins, from different families, affected by VVS and a family with several members with this condition. Their clinical characteristics, haemodynamic response to tilt, treatment, and outcome are described.

Background: This study intended to find out whether the parameters of heart rate variability (HRV) can predict the treatment efficacy of orthostatic training among pediatric cases of vasovagal syncope (VVS).
Methods: Patients with VVS who underwent orthostatic training were retrospectively enrolled. Lasso and logistic regression were used to sift through variables and build the model, which is visualized using a nomogram.

Article Synopsis
- The study aimed to assess autonomic nervous function in patients with vasovagal syncope (VVS) by comparing deceleration capacity (DC) and acceleration capacity (AC) between VVS patients and healthy controls.
- Significant differences were found, with VVS patients showing higher DC and lower AC values, as well as increased heart rate variability.
- DC and AC were recognized as independent predictors for syncope, suggesting that these measures could serve as useful indicators for evaluating cardiac autonomic dysfunction in clinical settings.

Aim: In light of many recent advances in the field of vasovagal syncope, a selective review has been undertaken of these developments.
Methods: Recent publications on the following topics were reviewed; understanding of vasovagal syncope pathophysiology, tilt-testing methodology and interpretation, drug, ablation and pacemaker therapy.
Results And Conclusions: The vasovagal syncope field is very active in researching its pathophysiology, using it to gain better understanding of the process and applying this knowledge to therapy.

Vasovagal syncope (VVS), characterized by transient loss of consciousness, is among the most prevalent reasons for emergency visits worldwide. Although benign in nature, VVS can be accompanied by traumatic injury, leading to morbidity and decreased quality of life, especially in those with VVS recurrence. The management includes non-pharmacologic and pharmacologic therapies (if resistant), patient education and reassurance, salt and fluid intake increase, and physical counter-pressure maneuvers.
