What is Heart Rate Variability (HRV)? As popular as the metaphor may be, a healthy heart doesn’t beat as regularly as a metronome — in fact, it changes its rhythm with each beat. This constant variation in milliseconds between your heartbeats is known as your heart rate variability, or...

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...
Heart rate variability is the slight difference in the amount of time between your heartbeats. Your heart rate variability is controlled by the balance between a couple of different parts of yourautonomic nervous system: the "fight-or-flight" response and your "rest-and-digest" response. In gen...

Heart rate variabfility (HRV) has been a focal point throughout my academic history. To put into perspective, I have published studies spanning seven decades focusing on HRV (1969鈥 2022). My interest in HRV started early in graduate school and continues to be an important portal informing ...
Heart Rate Variability (HRV)is a statistical analysis of the small variations in time intervals between heartbeats. These variations are a normal physiological phenomenon. Studies have shown that changes in HRV are associated with a wide range of diseases as well as pain, stress and obesity. ...
A healthy heart isn’t a metronome that keeps a regular rhythm: the time between each beat varies. While heart rate refers to the number of times your heart beats per minute. Heart rate variability (HRV) measures the fluctuation in the time intervals between adjacent heartbeats. This beat-to...
What is heart rate variability (HRV) and why it matters? HRV describes the variations between consecutive inter-beat-intervals or IBIs.
