Introduction to sinus arrhythmia in children

Children's health is an issue that mothers are more concerned about. Children are very vulnerable to some harm in some environments, that is, in an environment with serious pollution, loud noise, or malnutrition, they are very likely to suffer from some diseases. The symptom of sinus arrhythmia in children is a problem that many children have experienced. Although this symptom is not very harmful, it has a greater impact on children's health. Let's take a look at the introduction of sinus arrhythmia in children.

1. Causes

It is more common in healthy children, especially in children over 3 years old and less common in infants and young children. It often occurs when the heart rate is slow or during sleep, and the heart rhythm can become regular when the heart rate increases or when exercising or awake. Drugs such as digitalis, morphine, and beta-blockers can cause arrhythmia. It can also be seen in children with organic heart disease.

2. Clinical manifestations

Children's symptoms are milder than those of adults and they often lack complaints. Some older children may describe palpitations, chest tightness, and discomfort. Often detected by auscultation or electrocardiogram, sinus arrhythmia may be related to the respiratory cycle, which speeds up during inhalation and slows down during exhalation. Sinus arrhythmia was of no clinical significance.

3. ECG characteristics

(1) Respiratory sinus arrhythmia sinus P wave; the arrhythmia is related to breathing, slowing down during exhalation, speeding up during inhalation, and the heart rhythm becomes regular when holding the breath; on the same lead, the PP interval differs by more than 0.12 seconds;

(2) The symptoms of non-respiratory sinus arrhythmia are basically the same as those of respiratory sinus arrhythmia; the arrhythmia has nothing to do with the respiratory cycle.

Children's health issues require our parents' special attention. For a family, children are the future of the family and the source of power for family prosperity. Therefore, ensuring children's health is something parents should think about. Although sinus arrhythmia in children is not a serious disease, it cannot be ignored. Once it worsens, it will have serious consequences.
