Hello. Thank you for the question submitted to HealthReplies.com. We can understand the concern you feel.


Human heart rate is influenced by several factors, for example age and activity. In children aged 2-10 years, heart rate ranges from 70-110 times per minute at rest in a wake state. When resting in a sleep state, the heart rate of children aged 2-10 years ranges from 60-90 times per minute. When active, for example playing while running or crying, the heart rate of children aged 2-10 years can increase up to 220 times per minute. Heart rate can also increase due to the child's body condition, for example fever, mild-moderate dehydration, shortness, and others. Therefore, if the child's heart rate reaches 125 beats / minute, it is necessary to assess whether at the time of the measurement there are factors that influence the increase in frequency, for example body temperature, activity that has just been or is being carried out, etc.


Not only frequency, the quality of the heart rate also needs to be examined from the aspect of regularity, strength, and comparison of the pulse on the right-left side of the body and hands-feet. In principle, if a slight increase in heart rate is caused by physiological / normal factors and there are no significant complaints in children (for example: tightness, chest pain, weakness, dizziness, decreased awareness), you don't need to worry.


To assess whether your child's heart rate is right, you are advised to have your child checked directly by a doctor or pediatrician. To enrich insight, you can read articles about heart rate. Thus information from us. Hopefully always healthy. May be useful.
