HEART RATE VARIABILITY
Heart Rate Variability is one of the most important measures of heart health, but it’s rarely talked about. The variability of the heart rate means the
variation in the time between each heart-beat. This is different from your heart rate, which is measured by the number of times your heart beats per minute.
The variability of your heart rhythm refers to your hearts ability to adapt the heart rate up or down, as needed, throughout the day, depending on your activity and emotions.
