Sinus tachycardia and atrial tachycardia in children

Tachycardia generally refers to an abnormally rapid heart rate. Sinus tachycardia and atrial tachycardia in children are both types of arrhythmias, which may be associated with factors such as intense physical activity, iron-deficiency anemia, or myocarditis. These conditions can be managed through daily care, oral medications, and other treatments. Specific analyses are as follows:

1. Intense Physical Activity

If a child has engaged in strenuous exercise, sinus tachycardia or atrial tachycardia may appear during electrocardiogram (ECG) testing. However, the heart rate typically returns to normal after adequate rest, and no specific treatment is required. Parents should monitor and control their child's exercise intensity and duration to prevent physical discomfort.

2. Iron-Deficiency Anemia

If a child has habits of picky or selective eating, leading to insufficient nutrient intake, iron deficiency may occur in the body. This can impair hemoglobin synthesis, resulting in anemia, which in turn affects the heart's pumping function and may cause arrhythmias. Treatment may include taking iron supplements such as ferrous gluconate oral solution or iron dextran oral solution, as directed by a physician.

3. Myocarditis

If a child is infected with viruses or bacteria, the infection may affect the heart muscle and trigger myocarditis. The inflammatory response can impair oxygen and blood supply to the myocardium, causing symptoms such as palpitations, arrhythmias, and chest pain. Medications such as oseltamivir phosphate granules and vitamin C chewable tablets may be taken as prescribed to help alleviate symptoms.

In addition to the common causes mentioned above, tachycardia in children may also be related to congenital heart disease, hyperthyroidism, or heart failure. If a child experiences other accompanying symptoms, it is recommended to seek medical evaluation at a hospital for accurate diagnosis and targeted treatment.
