Key result
Familial vasovagal syncope was described in two groups of monozygotic twins and a family, detailing their clinical characteristics, haemodynamic response to tilt, treatment, and outcomes.
Case Report
This case series highlights the familial occurrence of vasovagal syncope, describing clinical and haemodynamic characteristics in affected twins and family members.
May inform family history assessment in vasovagal syncope; leaves open heritability and requires larger studies before practice change.
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.
