Rapid Heartbeat In Children: Common Causes And What Parents Should Know

It is quite common for children to experience episodes of rapid heartbeat, and there are multiple reasons behind this phenomenon. One of the most frequent causes is emotional stress, crying, or general restlessness. When these emotional factors are ruled out, an elevated heart rate often points to a fever. For every 1°C increase in body temperature, a child's heart rate may rise by approximately 15 to 20 beats per minute.

Medical Conditions That Can Cause Tachycardia In Children

Besides fever, certain respiratory conditions can lead to oxygen deficiency, which in turn may result in low oxygen levels in the blood. This can trigger a faster heart rate as the body tries to compensate. In some cases, underlying heart conditions such as myocarditis or cardiomyopathy may be responsible for an abnormally fast heartbeat. These conditions affect the heart muscle and its ability to function properly, causing the heart to work harder than normal.

Other Systemic Causes Of Rapid Heart Rate

Additionally, disorders like hyperthyroidism—an overactive thyroid gland—can also lead to tachycardia in children. Other systemic illnesses or imbalances in the body may similarly affect heart rhythm. Parents should be aware that while some causes are benign and temporary, others may require medical evaluation and treatment.

When To Seek Medical Attention

If a child experiences persistent or unexplained rapid heartbeats, it's advisable to consult a healthcare professional. Doctors can perform necessary tests to rule out serious conditions and provide appropriate treatment if needed. In many cases, once the underlying cause is identified and addressed, the heart rate returns to normal. There's no need for panic, but staying informed and seeking timely medical advice is key to ensuring a child's well-being.
