Tachycardia in children

Tachycardia in children


- My child, 10 and a half years old, every time he has a fever when he is cold, has a very big and strong pulse. Heartbeats are usually strong and not only when you have a fever. But tachycardia does when you have a fever over 38. Is it normal or should I take it to a cardiologist?


Tachycardia represents an increase in heart rate above a certain value considered normal, depending on age. Tachycardia can be functional (without pathological significance) in:

  • emotional states
  • the effort
  • during digestion
  • to increase the temperature of the environment.
    Tachycardia with pathological significance can be found in:
  • febrile, infectious diseases
  • bleeding,
  • anemia,
  • acute myocarditis,
  • heart failure,
  • congenital heart disease,
  • hyperthyroidism etc.
  • Thus, a tachycardia that appeared during a febrile illness is part of the clinical picture of these conditions and does not mean the presence of a pathology in the heart, a consultation with the family doctor is sufficient.
