During Heart Rate Variability?

Heart rate variability or HRV is the physiological phenomenon of the variation in the time interval between consecutive heartbeats in milliseconds. A normal, healthy heart does not tick evenly like a metronome, but instead, when looking at the milliseconds between heartbeats, there is constant variation.

How does HRV affect the body?

HRV can detect stress levels. People with low HRV can easily experience acute stress while people with high HRV rarely experience stress and their cardiovascular system is in great shape. Checking your HRV can help you understand how to respond to stress in a healthier way.

What heart rate variability means?

Heart rate variability is literally the variance in time between the beats of your heart. So, if your heart rate is 60 beats per minute, it's not actually beating once every second. Within that minute there may be 0.9 seconds between two beats, for example, and 1.15 seconds between two others.
