Syncope is very common and will affect 42% of people during their lifetime
Syncope in children and young adults
In early childhood:
- Vasovagal syncope in young children or Reflex Anoxic Seizures (RAS) - see more on vasovagal syncope in younger children.
- Cyanotic (or blue) breath holding spells or reflex expiratory apnoea syncope or infantile reflex expiratory apnoea syncope – this is a common phenomenon and tends to occur when children stop crying after prolonged crying
In late childhood and young adults:
- Vasovagal Syncope – there is a peak incidence of VVS around the age of 15, and it is twice as common in females compared to males
- Initial orthostatic hypotension
- Postural tachycardia syndrome – not all people with PoTS experience syncope
- Mess trick or the ‘Fainting Lark’– the person first hyperventilates while squatting, then standing up quickly, strains (valsalva manouevre) then faints
- Adolescent stretch syncope – a rare phenomenon seen in teenagers and young adults. It is due to hyperextension of the neck and mechanical compression of the vertebral arteries.
- SADS (Sudden Arrhythmia Death Syndrome) Foundation - Provides support and information for patients and families affected by SADS and aims to raise public awareness.
- CRY - Cardiac Risk in the Young - Works with cardiologists and GPs to promote and protect the cardiac health of young people by establishing good practice and facilities to reduce the frequency of young sudden cardiac death.
