Ectopic Beats - Abnormal Heart Beats (Children)

2026/01/27
What are Ectopic Beats?
The most common form of heart irregularity in children is the occurrence of an extra heartbeat. This extra beat is followed by a slight pause, leading to the perception of a missed heartbeat, and then often a more forceful beat. Ectopic beats are generally harmless and tend to disappear with physical activity. 

If there is a suspected heart rhythm problem, the paediatric heart doctor may recommend cardiac testing, including an electrocardiogram to check for abnormal rhythm, and even wearable heart monitor to capture symptoms over the course of a day or more.  

In the majority of cases, these are not life-threatening and may not require treatment unless advised by the doctor, depending on their frequency of occurrence.   
Signs & Symptoms
Often, individuals perceive ectopic beats as a sensation of the heart ‘missing a beat’. This is typically followed by what feels like a stronger heartbeat or a noticeable ‘thump’. These sensations are due to extra heartbeats, medically known as extra systoles or ectopic beats. 
Care Tips

Dental Care 

Good dental hygiene is essential, especially for children and adults with congenital heart disease, as poor dental health can lead to infections spreading to the heart. Therefore, regular dental check-ups are crucial. 

According to the latest guidelines, there is no need for antibiotic prophylaxis before dental procedures for children with ectopic beats.  

Exercise 

Exercise is beneficial, even for those with heart conditions. It improves heart function, overall well-being and is associated with increased life expectancy and reduced heart disease risk in later life. It also aids in weight control and in lowering blood pressure. 

Different types of exercise, such as static (e.g. weightlifting) and dynamic (e.g. running), have varying impacts on the body and heart. Children with heart conditions should consult their doctor to determine safe levels and types of exercise, especially in school settings where physical activities can be intensive. 

Vaccination 

Most children with heart disease can follow the standard vaccination schedule. However, those with immune deficiencies, such as DiGeorge syndrome or isomerism, or those who are receiving immunosuppression, such as post-transplantation, may require a modified vaccination schedule. 

Travel Advice 

Before travelling, especially long distances or to unusual destinations, we recommend to: 

  • Have a recent medical check-up 
  • Ensure appropriate insurance coverage 
  • Carry an adequate supply of medication 
  • Be informed about the local healthcare quality and accessibility 
  • Carry relevant documentation about the heart condition   
  • For cyanotic heart disease patients, be aware of potential oxygen needs during flights 

Use support stockings and take aspirin or an equivalent unless your doctor advises against it.

Diet 

Special diets are not normally required for those with heart disease, but a balanced one is important. Maintaining a normal weight is crucial as excess weight increases the heart’s workload. 

Infection 

Children with heart disease are generally not more prone to infections. However, some may be susceptible to chest infections or have associated immune deficiencies, particularly those with holes in the heart (ASD, VSD, PDA). Viral infections are common and usually resolve without antibiotics, but medical advice should be sought in case of uncertainty. 

Medication 

Not all children with heart disease require medication. Those who do may need it for fluid reduction, to aid heart pumping, for rhythm control, or for blood thinning. 

While these medications are generally safe, side effects can occur, especially with other illnesses or medication changes. Any unusual symptoms or side effects should be promptly reported to the doctor. 

Pregnancy 

Most women with heart disease can have a normal pregnancy and delivery. Exceptions may include those with severe cyanosis or pulmonary hypertension, where pregnancy can pose significant risks. 

It is essential to seek medical advice before pregnancy so the process can be monitored and, if treatment is necessary, provided early.
