What is the normal heart rate (HR) for a 6-year-old child?

Normal Heart Rate for a 6-Year-Old Child

The normal resting heart rate for a 6-year-old child is 70 to 115 beats per minute. 1, 2

Age-Specific Parameters

• For children after age 3 years, including 6-year-olds, the established normal range is 70-115 bpm at rest. 2
• This range represents a narrowing from younger ages, as children aged 1-5 years typically have slightly higher rates. 1
• The 6-year-old range aligns with evidence-based centile data showing median heart rates around 100-113 bpm for this age group. 3

Clinical Interpretation

• Heart rates consistently below 70 bpm or above 115 bpm at rest warrant further evaluation. 1
• Tachycardia (>115 bpm) in a 6-year-old can be an early sign of physiologic stress, appearing before other vital sign changes. 2
• Accompanying symptoms such as dizziness, fainting, chest pain, or shortness of breath with abnormal heart rates require immediate medical attention. 1

Factors That Modify Heart Rate

• Fever increases heart rate by approximately 10 bpm for each degree Celsius elevation. 1
• Stimulant-containing medications can elevate heart rate above normal ranges. 1
• Activity state matters: heart rates are higher when awake versus asleep, though the 70-115 bpm range applies to resting measurements. 4

Measurement Best Practices

• Multiple measurements over time provide more reliable information than a single reading. 1
• Electronic monitoring devices are reliable when used according to manufacturer instructions. 1
• Ensure the child is at rest (asleep or quietly awake) when measuring to obtain an accurate baseline heart rate. 4
