Key result
Non-invasive ECG indicators help predict the diagnosis and prognosis of vasovagal syncope in children.
Why the study?
Electrocardiographic indicators are accessible, inexpensive, and may help optimize diagnostic procedures and individualized treatment strategies in pediatric vasovagal syncope.
What is the predictive value of electrocardiographic indicators in the diagnosis and prognosis of children with vasovagal syncope?
What is the predictive value of electrocardiographic indicators in the diagnosis and prognosis of children with vasovagal syncope?
Electrocardiographic indicators offer an easily obtainable and inexpensive method to aid in the diagnosis and prognostic evaluation of pediatric vasovagal syncope.
May aid noninvasive stratification in pediatric vasovagal syncope; leaves open need for prospective validation before practice change.
Neurally mediated syncope (NMS) is a common type of syncope in children in clinical practice, among which vasovagal syncope (VVS) is the most frequent. In recent years, more and more studies have been carried out to assess the diagnosis and prognosis of VVS. The electrocardiographic indicators such as heart rate variability (HRV), QT dispersion (QTd), P-wave dispersion (Pd), ventricular late potentials (VLP), deceleration ability of heart rate (DC), etc., are easy to obtain and inexpensive. With the help of electrocardiographic indicators, the diagnostic procedure and individualized treatment strategies of pediatric VVS can be optimized. This article reviews the value of electrocardiographic indicators in the diagnosis and prognosis of children with VVS.

Zhao et al. (2022) conducted a review in Vasovagal syncope. Electrocardiographic indicators (HRV, QTd, Pd, VLP, DC) was evaluated. Electrocardiographic indicators such as heart rate variability, QT dispersion, and P-wave dispersion are easily available, non-invasive tools that can help predict the diagnosis and prognosis of vasovagal syncope in children.
