How much does your heart rate rise when you stand up? Compare your numbers with the criterion clinicians use for postural orthostatic tachycardia syndrome (POTS).
Enter both readings to see how your heart-rate rise compares with the criterion used for POTS.
Lie down and rest for 5–10 minutes, then note your heart rate — that's your resting reading. Stand up and stay still and quiet for up to 10 minutes, and note the highest heart rate you see. An Apple Watch, fitness tracker, or pulse oximeter all work. For a more structured version with timers and minute-by-minute readings, use our guided NASA lean test.
One criterion used for POTS in adults is a sustained heart-rate increase of 30 bpm or more within 10 minutes of standing, in the absence of orthostatic hypotension (a significant blood-pressure drop). For adolescents aged 12–19 the threshold is 40 bpm. Diagnosis also requires that symptoms have been present for months and that other causes are excluded — which is why a calculator can inform a conversation with your doctor, but never replace one.
