What Is Heart Rate Variability (HRV)?

As we all know, our heartbeat rhythm is not static but changes with each beat.This change in the difference between heartbeat cycles, or the subtle changes in heartbeat speed, is the so-called heart rate variability. Specifically, the heart is innervated by both the sympathetic and parasympathetic nerves (vagus nerve).These two nerves interact to continuously change the beating frequency and intensity of the heart.HRV varies under different circumstances, sometimes increasing and sometimes decreasing.
