which of the following is a common cause of cardiac arrest in children and infants

The most common cause of cardiac arrest in children and infants is respiratory failure leading to hypoxia , not a primary heart attack like in adults.

Quick Scoop

In pediatrics, cardiac arrest is usually the end result of breathing problems that gradually deprive the body of oxygen, rather than a sudden primary heart rhythm problem as often seen in adults. This means issues like severe asthma, choking, respiratory infections, or progressive respiratory failure often trigger the cascade that ultimately stops the heart.

What this typically looks like

• Progressive respiratory failure or shock is reported as the leading trigger of in-hospital pediatric cardiac arrest.

• Common upstream problems include:
  • Severe asthma attacks and other serious lung disease.

* Choking or airway obstruction.

* Serious infections affecting breathing (e.g., pneumonia) or the heart (myocarditis).

Other important pediatric causes

While respiratory failure is the most common pathway, other causes matter clinically and in exams:

• Congenital heart abnormalities (e.g., structural defects, cardiomyopathies, electrical disorders) are a major cause of sudden cardiac arrest in infants and children.

• Dangerous arrhythmias and electrical problems (like ventricular fibrillation) can also lead directly to arrest.

• Trauma (drowning, major injury, commotio cordis from a blow to the chest), poisoning, or severe allergic reactions are recognized but less common causes overall.

How this ties into typical exam options

When exam questions ask, “Which of the following is a common cause of cardiac arrest in children and infants?” and the choices mix adult-style causes (like classic myocardial heart attack) with pediatric ones (like respiratory failure, shock, or severe hypoxia), the correct answer is usually the option describing respiratory failure/hypoxia or shock rather than “heart attack” or “common cold.”
