The variances in your heart rate are very small, so it takes specialized equipment or devices to detect them. Best Practice The sympathetic and parasympathetic nervous systems regulate heart rate, blood pressure, temperature, digestion and other functions, allowing us to adjust these activities without conscious thought. PPG determines the timing of cardiac cycles via continuous monitoring of changes in blood volume in a portion of the peripheral microvasculature. So, if the heart rate is 60 beats per minute, it is not in reality beating once per second. Heart rate variability ( HRV) is the physiological phenomenon of variation in the time interval between heartbeats. One set of heartbeats may be at an interval of 1.3 seconds, whereas the next two may be at an interval of 0.7 seconds. We know that a heart rate that's too slow, too fast, or irregular can signal a problem, so it's only natural to think that a steady, regular pulse is a sign of a healthy heart.
