Child's Racing Heart? Dr. Bajpai Explains Warning Signs

Many parents become concerned when their children report a racing heart, particularly during physical activities like sports. While a gradually increasing heart rate that subsides with rest is normal, cardiologist Dr. Pankaj Bajpai notes that a sudden, unprovoked 'pounding' sensation could signal an issue. If this racing heart is accompanied by dizziness, chest pain, paleness, or disproportionate breathlessness, it may indicate an arrhythmia requiring a cardiac evaluation.

Fainting is another symptom that warrants careful consideration. Dr. Bajpai explains that fainting after standing for long periods or standing up quickly is usually benign. However, fainting during intense physical exertion, not at rest, could point to an unstable heart rhythm or underlying structural problems such as hypertrophic cardiomyopathy. In such cases, sports should be stopped immediately until a medical evaluation is completed.

Confirming a cardiac issue typically involves a cardiologist's assessment, including a detailed history of the episode. Diagnostic tools may include a resting ECG, echocardiogram to check for structural problems, or an exercise stress test for intermittent symptoms. Parents are urged to proactively share their family medical history, especially any instances of unexplained sudden death before age 50 or known congenital heart conditions.

Dr. Bajpai emphasizes that while many cardiac causes in children are manageable when caught early, accurate identification is key. He advises parents to observe symptoms, note triggers, and seek professional cardiac opinions rather than attempting to self-diagnose potentially alarming episodes.
