Models for differentiating between vasovagal syncope and psychogenic pseudosyncope in children

Takeaway

  • Study developed and established accuracy of a new scoring method for differentiating vasovagal syncope (VVS) from psychogenic pseudosyncope (PPS) in children using only three variables (QT-dispersion, syncope duration and upright posture).

Why this matters

  • VVS and PPS share many clinical similarities yet are very different diseases, requiring different management and treatments. Accurate diagnosis is therefore critical.

  • This study highlights a 3-variable scoring method which is able to provide an initial diagnosis differentiating VVS from PPS in children. As it is non-invasive, of low expense and easy to perform, it could be of great value if implemented.
