HRV by age: where does your reading sit?
Short answer: Pick your age and sex and enter an HRV reading in milliseconds. The tool compares it with the median resting RMSSD for your group from the Lifelines Cohort Study. Normal ranges are wide and devices measure differently, so use it for context and track your own trend for decisions.

Questions people also ask
Can I enter my Apple Watch HRV?
You can, but Apple Health reports SDNN while this chart uses RMSSD from short resting ECGs, so treat the comparison as rough. Your trend against your own baseline matters more.
My HRV is below the median. Is that bad?
Not necessarily. Half of healthy people are below the median by definition, and the normal range is very wide. A sustained drop from your own usual level is more informative. If you have symptoms, talk to a doctor.
