Faints & Syncope

Fainting is common in childhood and usually harmless — but certain patterns deserve careful cardiac evaluation.

When to Seek Evaluation

Which Faints Need a Specialist?

Syncope is a brief loss of consciousness caused by a temporary fall in blood flow to the brain. Most childhood faints are simple vasovagal episodes. A structured cardiology review is recommended when there are:

  • Repeated or unexplained fainting episodes
  • Faints during exercise or exertion
  • Palpitations or chest pain before the episode
  • A family history of sudden cardiac death or inherited heart disease
  • An abnormal ECG picked up at school or sports screening

What we look for.
The evaluation distinguishes vasovagal syncope and orthostatic hypotension from arrhythmias (SVT, long QT syndrome, CPVT), structural disease (hypertrophic cardiomyopathy, anomalous coronary artery, myocarditis) and non-cardiac causes such as seizures or low blood sugar.
Support between visits.
Established families have access to advice for urgent concerns and telehealth follow-ups where appropriate.
Structured Work-Up

How Faints Are Investigated

History & Examination

A meticulous account of each episode — triggers, warning signs, recovery — often points strongly to the diagnosis.

12-Lead ECG

Screens for electrical conditions such as long QT and Brugada syndrome in minutes.

Holter / Event Monitoring

24–72 hours of continuous rhythm recording during normal daily life.

Tilt-Table Testing

A safe, monitored way to reproduce episodes and confirm vasovagal syncope.

Ambulatory BP Monitoring

24-hour blood pressure monitoring helps identify blood-pressure-related causes of dizziness.

Echocardiogram

Ultrasound imaging of the heart excludes structural causes.

Common Questions

Syncope Questions

Is tilt-table testing safe for children?

Yes. The test is performed under continuous monitoring with experienced staff, and is stopped immediately if your child feels unwell. It is a well-established, safe investigation for recurrent fainting.

Can my child play sport while being investigated?

It depends on the pattern of the faints. Faints during exercise need evaluation before returning to sport; typical vasovagal faints usually don't require restriction. Dr Jain will give you clear, individual guidance at the first visit.

How long is the first appointment?

Initial consultations are 30 minutes, allowing a focused history, examination, an ECG where indicated, and time for your questions.
