Question:

I would like to ask about my 8-year-old child's heart rate. When they are sitting still and watching TV, their heart rate is about 120 beats per minute (bpm). When they are sleeping, it is between 90 and 100 bpm. Is this normal? My child also mentioned that their heart feels like it is beating fast, which makes me quite worried.


Answer:

I understand you are worried about your 8-year-old child's heart rate, especially since they mentioned feeling their heart beating fast.


Based on the numbers you provided:

• Resting (watching TV): 120 bpm

• Sleeping: 90-100 bpm


For an 8-year-old child, the normal heart rate ranges are typically:

• Resting: 70-100 bpm

• Sleeping: 60-90 bpm


Your child's current measurements are slightly higher than the normal range. However, rather than judging solely by the numbers, it is important to observe their overall condition.


When to seek immediate medical attention:

• Chest pain, dizziness, or fainting

• Severe shortness of breath or looking pale during physical activity

• Feeling an irregular heartbeat


Things to check at home:

  1. Accurate measurement: Measure the pulse for 1 full minute after the child has been resting calmly for at least 5 minutes.

  2. Other symptoms: Check if they are experiencing fatigue, headaches, or anxiety.

  3. Recent changes: Consider if there has been any recent caffeine intake (like sodas or chocolate), stress, or lack of sleep.


Since your child is experiencing the sensation of a fast heartbeat (palpitations) and the measured heart rate is on the higher side, it is highly recommended to visit a pediatrician. A simple electrocardiogram (ECG) can easily and accurately evaluate your child's heart to ensure everything is okay.
