Heart rate variability

Heart rate variability (HRV), also known as heart rate variability, describes the variation in time intervals between successive heartbeats.

In other words, instead of being a metronome that beats a perfect, steady rhythm, your heart beats in a variable pattern. The time between each beat varies slightly, and this variation is measured as HVR.

The greater the variation, the better it generally is. This indicates that your heart can respond flexibly to the demands of your body, both physical and mental. A high HVR is associated with a healthy nervous system, good health and stress resistance.

Conversely, a low HVR indicates a stressed or overloaded nervous system. This can be due to various factors, such as physical or emotional stress, poor sleep quality or certain illnesses.
