heart rate variability(HRV for the Spanish sigmas or HRV for the English abbreviation) is a phenomenon that we can measure with the Apple Watch. A measurement that may be suitable to show our health status and the condition of our heart. It’s a valuable metric worth knowing, and one that the Apple Watch measures accurately.

What is heart rate variability, HRV or HRV?

Heart rate variability (HRV or HRV), changes in the time interval between heartbeats. These intervals, known as RR intervals (the time between successive heartbeat peaks on an electrocardiogram), are not completely regular, even in healthy people.

It is an indicator of HRV capacity. autonomic nervous system (SNA) is used to adapt to different physiological demands and can be considered a relevant measurement in fields such as sports training, stress management, and monitoring general health.

Heart rate variability (HRV) measures the change in time between heartbeats. Apple Watch calculates HRV using the standard deviation of beat-to-beat measurements captured by the heart rate sensor. VFC is valid for users over 18 years of age. Third-party apps and devices can also add HRV to the Health app.

Why is heart rate variability (HRV or HRV) important?

According to the Cleveland Clinic, your heart’s variability reflects: How adaptable your body can be. If your heart rate is highly variable, this is often evidence that your body can adapt to many changes. People with high heart rate variability tend to be less stressed and happier.

Apple Watch can measure numerous parameters of our health

How to read heart rate variability, HRV or HRV with Apple Watch?

HE Apple Watch can measure heart rate variability without us having to do anything. It is a value that you calculate when you make different automatic measurements on a daily basis. These measurements are saved in the Health app, and to reference them you need to:

1. Enter the app on iPhone Health.
2. Tap the section below To discover.
3. Enter the section Heart.
4. You should see a section called heart rate variability.
5. You can also use the search engine to find this data in Explore.

When you enter you will see a graph showing the variability of your heart rate over days, weeks, months or years. Heart rate variability is measured in milliseconds and the value will be higher or lower depending on factors such as age or physical fitness.

What are normal values ​​for heart rate variability, HRV, or HRV?

Normal heart rate variability values ​​generally start from 100 ms in the first decade of our lives, An average decrease of around 10 ms every 10 years. While these may vary depending on user type, these will be normal values ​​depending on age:

• Between 20 and 30 years: 80ms.
• 30 to 40 years old: 70ms.
• 40 to 50 years old: 60ms.
• 50 to 60 years old: 50ms.
• 60 to 70 years old: 40ms.

This is roughly the average heart rate variability across these age ranges. Always It would be better to have an HRV or HRV above averagehowever, in addition to age, other factors such as gender or physical fitness may also affect it.

This is a very important value, such as heart recovery, which is closely related to measuring heart rate or blood oxygen level. Apple Watch also has the ability to perform electrocardiograms or detect sleep apnea, making it a device that monitors health in a variety of ways.
