Syncope Q & A What is syncope?

Syncope, or fainting, refers to a short loss of consciousness that occurs due to inadequate blood supply to the brain. Most of the time, syncope isn’t serious. However, if your child experiences syncope, you should seek an evaluation because it can indicate the presence of a severe medical condition.

Does pediatric syncope have other symptoms?

In addition to fainting, your child may experience the following signs and symptoms:

  • Lightheadedness or dizziness
  • Nausea
  • Vision changes
  • Cold, clammy skin

The team at Children’s Cardiology Group recommends that children drink water and sit with their head between their knees or lie down with their legs elevated for 10-15 minutes following a syncope episode.

What causes syncope?

Several conditions can lead to a decrease in blood flow to your child’s brain. Some of these include:

  • Vasovagal syndrome, a nerve condition
  • Arrhythmia, a slow, fast, or irregular heart rhythm
  • Structural heart defects in cardiac muscle or valves
  • Head injuries
  • Inner ear problems
  • Dehydration
  • Low blood sugar

Orthostatic hypotension, a drop in blood pressure that occurs when changing between sitting and standing positions, can also result in syncope.

How does a cardiologist diagnose syncope?

To determine the cause of syncope in children, the experts at Children’s Cardiology Group perform a physical exam, review your child’s health history, and check their blood pressure and heart rate. They also ask you questions about your child’s nutrition, hydration, and what they were doing right before they fainted.

Your provider may also order diagnostic tests, such as an electrocardiogram (ECG), which analyzes the electrical activity of the heart to detect arrhythmias, or an echocardiogram, which uses ultrasound to create a full image of your child’s heart.

How does a cardiologist treat syncope?

Once your cardiologist determines the exact cause of syncope, they recommend an appropriate treatment. For cardiac conditions that cause syncope, treatment may involve medication or an interventional cardiology procedure to address structural or electrical problems within the heart.

If another condition causes your child’s syncope, your cardiologist may recommend that they see another specialist, such as a pediatric neurologist.
