Normal Heart Rate for Children

Age-Specific Heart Rate Ranges

• The normal heart rate for a 6-year-old child ranges from 70 to 115 beats per minute (bpm) at rest, according to the American Academy of Allergy and Clinical Immunology 1
• By ages 1 to 5 years, the normal QRS axis is generally between 10° and 110°, indicating proper cardiac conduction, as recommended by the American College of Cardiology 2

Factors Affecting Heart Rate in Children

• Fever typically increases heart rate by approximately 10 bpm for each degree Celsius elevation in body temperature, as reported by the European Heart Society 4
• Medications, including those containing stimulants, can affect heart rate, according to the European Heart Society 4

When to Be Concerned

• Heart rates consistently below 70 bpm or above 115 bpm at rest in a 6-year-old may warrant further evaluation, as suggested by the American Academy of Allergy and Clinical Immunology 1
• Symptoms such as dizziness, fainting, chest pain, or shortness of breath accompanying abnormal heart rates require immediate medical attention 3

Measurement Considerations

• Electronic monitoring devices are reliable but should be used according to manufacturer instructions, as stated by the Praxis Medical Insights 3
• Multiple measurements over time provide more reliable information than a single reading, according to the Praxis Medical Insights 3
