Can children suffer cardiac arrest? Yes — and it’s more common than many parents realize. Learn the causes, symptoms, and how early intervention can save lives.

When most people hear the term cardiac arrest, they picture an adult clutching their chest — not a child. But contrary to common belief, children can suffer cardiac arrest, and when it happens, it’s almost always a medical emergency that requires immediate action.

 

What Is Cardiac Arrest?

Cardiac arrest occurs when the heart suddenly stops beating effectively, preventing blood from circulating to the brain and other vital organs. Without quick treatment, it can lead to death within minutes.

While it’s more commonly associated with adults, cardiac arrest can occur at any age — even in infants and toddlers.

 

Causes of Cardiac Arrest in Children

CA in kids often stems from different issues than in adults. Some of the most common causes include:

Congenital heart defects: Some children are born with structural heart problems that may not show symptoms until a sudden crisis occurs.

 

Arrhythmias: Abnormal heart rhythms, like Long QT Syndrome, can cause the heart to stop unexpectedly.

 

Myocarditis: An inflammation of the heart muscle, often triggered by a viral infection.

 

Commotio cordis: A rare event where a sudden blow to the chest (e.g., during sports) causes the heart to go into an arrhythmia.

 

Respiratory failure: Lack of oxygen due to choking, drowning, or severe asthma can also lead to cardiac arrest.

Warning Signs Parents Shouldn’t Ignore

Often, there are few or no warning signs before cardiac arrest in children, especially if the cause is a silent condition. However, here are symptoms that could indicate a developing cardiac issue:

• Sudden collapse or fainting during physical activity
• Chest pain or discomfort
• Rapid or irregular heartbeat
• Dizziness or lightheadedness
• Shortness of breath
• Unusual fatigue

If any of these symptoms occur — particularly during or after exercise — they should be treated as red flags.

 

What Happens During Pediatric Cardiac Arrest?

In the event of cardiac arrest, the heart stops pumping blood effectively. The child will:

• Lose consciousness
• Stop breathing or gasp for ai
• Have no pulse

 

Without immediate CPR and defibrillation, brain damage and death can occur within minutes.

 

What Parents and Caregivers Should Do

If a child collapses and is unresponsive:

1. Call emergency services immediately.

2. Start CPR right away — push hard and fast in the center of the chest.

3. Use an AED (automated external defibrillator) if one is available. AEDs are often found in schools, gyms, and public spaces and are safe for children.

Early action can double or triple the child’s chance of survival.

 

Can It Be Prevented?

Not all cases are preventable, but some steps can reduce risk:

• Have children screened for heart conditions if there is a family history.
• Ensure physicals are up to date, especially before sports.
• Know CPR and make sure your child’s school or daycare has trained staff.
• Support legislation and funding for pediatric defibrillators in schools and sports facilities.

 

Yes, kids can have CA — and while rare, it’s a critical situation that demands awareness and readiness. Education, early screening, and quick response can save lives.

 

As more families become informed and proactive, we can help ensure that children at risk are identified early — and more lives are protected.
