Few numbers on a health monitor prompt more questions than your heart rate — especially when it seems high or low for your age. Most adults have a resting pulse between 60 and 100 beats per minute, a range the American Heart Association (leading U.S. heart health organization) considers normal.

  • Check your resting heart rate in the morning before getting out of bed (Mayo Clinic Health System)
  • See a doctor if resting heart rate is above 100 or below 60 and you have symptoms like fainting or chest pain (Cleveland Clinic)

Four key numbers capture the essentials, and the pattern is clear: the younger you are, the faster your heart beats at rest, while for adults the range narrows.

Age group Normal resting heart rate
Adult (18+) 60–100 bpm
Newborn (0–1 month) 100–160 bpm
70-year-old (target exercise) 50–85% of max heart rate
Danger zone (resting) >120 bpm or <40 bpm

What is a normal heart rate by age?

Resting heart rate by age group

Cleveland Clinic (nationally ranked hospital) provides a detailed breakdown of normal resting heart rates from birth through adolescence. The pattern is consistent across sources: newborns start at 100–160 bpm, infants drop to 80–140, toddlers 80–130, preschoolers 80–120, school-age children 75–118, adolescents 60–100, and adults settle at 60–100 bpm.

Normal heart rate in children vs adults

  • Newborn (0–1 month): 100–160 bpm (MedicineNet (health information resource))
  • Infant (1–12 months): 80–140 bpm (Cleveland Clinic)
  • Toddler (1–3 years): 80–130 bpm (MedicineNet)
  • Preschool (3–5 years): 80–120 bpm (Cleveland Clinic)
  • School (5–12 years): 75–118 bpm (Cleveland Clinic)
  • Adolescent (13–17 years): 60–100 bpm (Cleveland Clinic)
  • Adult (18+): 60–100 bpm (American Heart Association)
Bottom line: The younger the child, the higher the normal range. Once you hit the teen years, the adult standard applies – but individual variability still matters.

What is a good pulse rate for a 70 year old?

Target heart rate for older adults

For a 70-year-old, a resting heart rate between 60 and 100 bpm is still considered normal, according to both Cleveland Clinic and the American Heart Association. During exercise, the picture shifts: maximum heart rate is roughly 220 minus age – 150 bpm for a 70-year-old – and the target zone for moderate activity is 50% to 85% of that max. Brigham and Women’s Hospital (leading teaching hospital) places the target range at 75 to 113 bpm for a 70-year-old using a 50–75% zone.

What to consider when checking pulse in seniors

  • Resting rate above 100 bpm while at rest is considered tachycardia and warrants a check-up (Cleveland Clinic)
  • Resting rate below 50 bpm can be dangerous if accompanied by dizziness or fatigue (Mayo Clinic Health System)
  • Medications such as beta-blockers can lower resting heart rate, so always interpret numbers in context (American Heart Association)
Bottom line: For a 70-year-old, the resting normal is still 60–100 bpm, but the exercise target narrows to 75–113 bpm. Any persistent deviation from these numbers, especially with symptoms, should be checked.

What is an unsafe heart rate by age?

Heart rate danger zones for different ages

Age group Danger zone (high) Danger zone (low)
Adults (18+) Resting >100 bpm (tachycardia) Resting <60 bpm (bradycardia) – dangerous if symptomatic
Children (3–5 years) Resting >120 bpm may need evaluation Resting <60 bpm with symptoms
Adolescents (13–17) Resting >100 bpm is concerning Resting <50 bpm with fatigue or fainting

Healthline points out that a resting heart rate above 120 bpm or below 40 bpm is a red flag regardless of age and should prompt immediate medical attention.

When to call a doctor

  • Heart rate consistently above 100 bpm at rest
  • Heart rate below 50 bpm with dizziness, shortness of breath, or fainting
  • Sudden changes in heart rate accompanied by chest pain or confusion (American Heart Association)
Bottom line: A resting heart rate above 100 bpm (tachycardia) or below 60 bpm (bradycardia) is a signal that something may be off, but the true danger zone is above 120 or below 40, especially when symptoms appear.

What is a red flag heart rate?

Red flags for heart rate in adults

According to Cleveland Clinic, red flag signs include a resting heart rate above 120 bpm or below 40 bpm, an irregular pulse that feels like it’s “skipping beats,” and any heart rate combined with fainting, chest pain, or shortness of breath. For community nurses and caregivers, a change in heart rate with fever or infection can be an early sign of sepsis.

Red flags for community nurses

  • Heart rate too low for age (below 50 bpm in adults) with confusion or lethargy
  • Heart rate too high (above 120 bpm) with fever or rapid breathing
  • Irregular pulse with any symptom of poor perfusion (Mayo Clinic Health System)
What to watch

For a 75-year-old, a resting pulse of 48 bpm while on beta-blockers may be harmless, but the same number in a healthy 40-year-old could signal an electrical problem. Always pair the number with the person’s symptoms and medication list.

What is the difference between normal vs dangerous heart rate?

Normal vs dangerous heart rate chart

Six age groups, one pattern: the danger zones at the extremes are consistent, but the “normal” middle narrows as you age.

Age group Normal resting (bpm) Dangerous (bpm)
Newborn (0–1 month) 100–160 <80 or >180
Infant (1–12 months) 80–140 <70 or >170
Toddler (1–3 years) 80–130 <60 or >150
Preschool (3–5 years) 80–120 <60 or >140
School (6–12 years) 75–118 <50 or >130
Adolescent (13–17) 60–100 <40 or >120
Adult (18+) 60–100 <40 or >120

The implication: for adults, any resting rate above 120 bpm or below 40 bpm is a red flag that warrants urgent evaluation. Children tolerate higher rates normally, so the dangerous thresholds shift upward.

Why this matters

A dangerous heart rate can signal arrhythmia, infection (sepsis), or heart disease. For older adults especially, an unexplained increase of 20+ bpm above their normal resting rate is often the first clue of an underlying infection.

Confirmed facts

  • Normal resting heart rate for adults is 60–100 bpm (NIH, AHA)
  • For children, normal ranges increase as age decreases
  • Dangerous heart rates are >120 bpm or <40 bpm (symptomatic)

What’s unclear

  • Exact danger threshold for very low heart rate varies person-to-person
  • Sepsis heart rate threshold for older adults is not precisely defined in public literature

Expert perspectives

“A normal resting heart rate for adults ranges from 60 to 100 beats per minute.”

American Heart Association (target heart rates chart)

“A heart rate that is too high or too low can be a sign of a heart problem or other medical condition.”

Cleveland Clinic (heart rate overview)

“For older adults, a gradual increase in resting heart rate over time should be monitored, as it may indicate decreased cardiovascular fitness.”

Frequently asked questions

What is a normal resting heart rate for a 70-year-old?

A normal resting heart rate for a 70-year-old is 60–100 bpm, the same as for most adults. However, many healthy seniors have a resting rate on the lower end due to medication or better fitness.

What heart rate is considered dangerous for a 70-year-old?

A resting heart rate above 120 bpm or below 40 bpm is dangerous for a 70-year-old, especially if accompanied by dizziness, chest pain, or shortness of breath.

What should a 75-year-old’s pulse be?

A 75-year-old’s resting pulse should be between 60 and 100 bpm. During exercise, the target zone is 73–110 bpm (50–75% of max heart rate of 145 bpm).

What is a red flag heart rate for older adults?

Resting heart rate above 120 bpm or below 40 bpm is a red flag, as is an irregular pulse with fainting or chest pain.

What are the signs your heart is in danger?

Signs include a resting heart rate consistently above 100 bpm, below 50 bpm, or an irregular pulse combined with fatigue, swelling, shortness of breath, or a dry cough.

What is the difference between normal and dangerous heart rate?

Normal resting heart rate for adults is 60–100 bpm. Dangerous is above 120 bpm (tachycardia) or below 40 bpm (bradycardia with symptoms). Danger thresholds are slightly higher for children.

Can a high resting heart rate be fixed?

Yes, lifestyle changes such as regular exercise, stress management, and hydration can lower a resting heart rate. Medications may be needed if the cause is a medical condition.

For anyone over 60, the monitoring implication is clear: track your resting heart rate weekly, especially in the morning, and note any sudden rise of 20+ bpm. That single number could be the earliest sign of infection or heart trouble – and catching it early means a better outcome.
