How much does the heart rate change?
Heart rate variability is actually the time difference between your heartbeats. So, if your heart rate is 60 beats per minute, it’s not actually beating every second. For example, in that minute, there may be 0.9 seconds between two beats and 1.15 seconds between the other two.
What variables affect heart rate?

- stand up. It may soar for about 20 seconds after you first get up from sitting down.
- mood. …
- body size. …
- drug. …
- Caffeine and nicotine.
Bad heart rate variability?

How reliable is heart rate variability?
Considered reliable in individual resting HRV measurements in adults: RMSSD (r = 0.20–0.98)pNN50 (r = 0.43–0.97), 5,10 HF (r = 0.48–0.96), LF (r = 0.60–0.97), and TP (r = 0.52–0.97).
What is normal heart rate variability?
Normal HRV in adults can vary anywhere From under 20 to over 200 ms.*The best way to determine your normal level is to use a wearable device, measure your HRV in a controlled environment (like sleep) and establish a baseline over a few weeks.
