19 wrz 2024 · Heart rate variability is the variation in the length of time between heartbeats, measured in milliseconds. It is different from heart rate. Heart rate variability results from the actions of your autonomic nervous system (ANS). The ANS controls your heartbeat, breathing, and digestion.
28 wrz 2017 · Heart rate variability (HRV) is the fluctuation in the time intervals between adjacent heartbeats (1). HRV indexes neurocardiac function and is generated by heart-brain interactions and dynamic non-linear autonomic nervous system (ANS) processes.
Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval.

26 maj 2024 · Heart rate variability (HRV) measures the difference in time between your heartbeats. A high or low HRV may indicate an underlying health concern.
1 wrz 2021 · Overview. What is heart rate variability? Heart rate variability is where the amount of time between your heartbeats fluctuates slightly. These variations are very small, adding or subtracting a fraction of a second between beats. These fluctuations are undetectable except with specialized devices.
Heart rate variability (HRV) is the measure of variations between consecutive heartbeats. HRV is controlled by your autonomic nervous system (ANS). Among other things, your ANS regulates involuntary body functions, such as your heart rate, blood pressure, temperature, respiratory rate, etc.
