To assess whether isolated very low QRS voltage of ≤0.3 mV in the frontal leads might be a marker for diagnosing paediatric vasovagal syncope and the risk of recurrence. We included 118 children with vasovagal syncope, comprising 70 males and 48 females in our retrospective analysis. All patients un...
