Heart rate variability (HRV) is the variation in the time between two consecutive heartbeats over a specific period. Doctors may use HRV as an indicator for certain aspects of a person’s health, ...

Heart rate variability typically decreases during stressful situations, although the heart rate increases. Managing stress levels can mean a more variable heart rate. Exercise and relaxation ...

A post hoc analysis found that the effect of transcutaneous auricular vagus nerve stimulation (taVNS) on cardiac and inflammatory stress responses was critically dependent on variability in baseline ...

This article was originally featured on The Conversation. Your heart beats around 100,000 times every day. Heart rate is a key marker of cardiovascular activity and an important vital sign. But your ...

Heart rate variability (HRV) typically increases with parasympathetic activation (rest-and-digest response) and decreases with sympathetic activation (fight-or-flight response). The autonomic nervous ...

A recent study published in the journal Scientific Reports observed that maternal heart rate variability (mHRV) at three months postpartum is associated with infant neurophysiology and maternal mental ...

It’s been known for decades that heart rate variability (HRV) during labor signals how a fetus is responding to stress. Lower HRV—a lower variation in heartbeats—is even a risk factor for sudden ...

A recent study showed that the heart rate variability of a dog and its owner adapt to each other during interaction. High heart rate variability is associated with relaxation, while low heart rate ...
