Researchers have used mathematical analysis tools to study the effect of classical music on a fetal heartbeat and identify patterns in heart rate variability. They recruited 36 pregnant women and ...

Playing music has long been a way for expectant parents to connect with their children in the womb, but a group of researchers has found evidence it can calm fetal heart rates, potentially providing ...

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, ...

What is heart rate variability (HRV)? As popular as the metaphor may be, a healthy heart doesn’t beat as regularly as a metronome. In fact, it changes its rhythm with each beat. Heart rate variability ...

A hair-thin, soft robotic probe inserted through existing surgical ports to continuously track multiple fetal vitals in real time. Northwestern University researchers have developed the first device ...
