Get same-day care for a very high or very low heart rate

  • A resting heart rate above about 120 to 130 bpm, or a new heart rate below 40, should be checked the same day.
  • Call 911 or your local emergency number for chest pain, fainting or trouble breathing.
  • Fever, dehydration and some medicines can raise your heart rate. A reading this far from usual still needs same-day care.

When to see a doctor

Few people your age have a resting heart rate this high. Sit quietly for a few minutes and check again. If it's still this high, talk with your doctor soon, even if you feel well.

Call 911 or your local emergency number right away if your heart rate is suddenly very high or very low and you have chest pain, shortness of breath, dizziness or fainting.

Is 143 bpm normal at every age?

Children's hearts beat faster, so the same heart rate can mean different things at different ages.

Your age group is listed first. Percentiles come from a national CDC health survey from 1999–20081. For ages 12 and older, the normal range is 60 to 100 bpm, from the American Heart Association2. For younger children, typical means between the 5th and 95th percentiles. Well below or well above usual means lower or higher than 99 out of 100 people the same age.

What 143 bpm means for you

143 bpm is 72 bpm above the 71 bpm median for adults ages 20 to 39.

Why it changes. Your resting heart rate goes down with regular aerobic exercise. It goes up with stress, fever, dehydration, caffeine, nicotine and some medicines. A reading taken right after climbing stairs or drinking coffee can be 10 to 20 bpm higher than your true resting heart rate.

Look for trends, not one number. If your watch or fitness tracker shows a change from your usual resting heart rate that lasts for days, make a note of it. Mention it at your next checkup.

How to take your resting heart rate

  1. Sit quietly for 5 minutes. Skip caffeine and exercise for an hour before.
  2. Place two fingertips on the thumb side of your inner wrist.
  3. Count the beats for 30 seconds and multiply by 2.
  4. Repeat on 2 or 3 mornings and use the average.
  5. At 143 bpm, you'd count about 72 beats in 30 seconds.

Common questions

Short answers about how these calculators work.

143 bpm is well above usual for adults ages 60 to 79. It's higher than 99 out of 100 people in this age group.

No. A lower resting heart rate often comes with regular aerobic exercise. But a very low reading can also come from a medicine or a heart rhythm problem. How you feel, and whether the number is new for you, matters more than the number alone.

A watch can show you a trend. A true resting heart rate is counted at the wrist after you sit quietly for 5 minutes. Use a watch reading only if it was taken while you were resting, not walking.

For anyone 12 and older, a resting heart rate above 100 bpm is above the normal adult range. A reading higher than 99 out of 100 people your age is well above usual. Fever, dehydration, caffeine and some medicines can raise it.
