Heart rate variability (HRV) is the complex modification of the heart rate by the coordination of autonomic, respiratory, circulatory, endocrine and mechanical influences over time. Originally popularized as a research tool to detect fetal distress,1and later to predict risk of mortality post-myocardi...

Your Crash in a Graph? How Heart Rate Variability Testing Could Help You Improve Your HealthMy husband now asks me almost every day how my numbers are – and it makes sense to him. That makes HRV an amazing tool as far as I am concerned! Karminpoor sleep...
Heart Rate Variability (HRV) One of the first things to know when understanding heart rate is that the most informative metric relies not just on the heart rate, but how much the heart ratevaries. What’s often at first glance counter-intuitive about this metric is that ahigherheart rate ...
Heart rate variability biofeedback (HRVB) has been used for a number of years to treat depressive symptoms, a common mental health issue, which is often comorbid with other psychopathological and medical conditions. The aim of the present meta-analysis is to test whether and to what extent HR...
Furthermore, PPG can be used to index heart rate variability (HRV), blood pressure, oxygen saturation, and cardiac output24, but as of yet have not be widely rolled out in consumer-use devices and therefore data collection other than HR will not be discussed further. Table 1 Summary of ...

Heart rate (HR) and heart rate variability (HRV) were measured during a public speaking task in 51 young adults with ASD and 28 typically developing (TD) controls. The results showed no significant group differences in baseline HR/HRV, HR reactivity (change from baseline to the speaking task...
Counter intuitively the higher your heart rate variability, the healthier you are. People think that if your heart rate is 60 bpm then your heart is beating once per second but this is not the case. In fact if it were, you would be very ill. An example of normal heart beat intervals ...
