Heart rate variability, often shortened to HRV, describes variation in the time interval between successive heartbeats. It is influenced by autonomic nervous system activity and can be measured in several different ways.
A number needs context
HRV can vary with age, breathing, sleep, exercise, stress, time of day, measurement length and the device being used. Because protocols differ, one reading should not be treated as a standalone diagnosis.
Consistent measurement conditions and changes over time can provide more useful context than comparing your result with somebody else’s.
How Alma Health uses objective information
Where relevant, objective testing can add another layer of information to your history and physical assessment. Results should be explained clearly and considered alongside the whole clinical picture.
HRV does not replace medical assessment, and concerns about heart rhythm, chest pain, fainting or breathlessness should be discussed promptly with an appropriate medical professional.
