What is a normal heart rate?
Last updated September 3, 2026.
60 to 100 beats per minute at rest for most adults, per MedlinePlus - with the asterisk that trained athletes legitimately rest in the 40s-50s: a strong heart moves more per beat, so lower can mean fitter. Context rules: exercise, stress, caffeine, fever, dehydration, and medications all move the number, so measure seated, quiet, five minutes rested. The patterns worth attention: resting rates persistently over 100 or under 60 with symptoms; racing without reason; and rhythm - skipping, fluttering, or irregular racing deserves an EKG, because rhythm problems matter more than rate alone. The red line: racing pulse plus chest pain, severe breathlessness, or fainting is an emergency. Pymander is a free AI doctor, 24/7 by text, and can help you interpret your readings.
What to do
- Measure at rest: five quiet minutes, seated, 30 seconds doubled.
- Watch pattern, not moments: persistent beats episodic.
- Irregular beats fast or slow: rhythm problems need an EKG.
- Racing plus chest pain or fainting? Emergency.
