Abstract: Objective: Heart rate variability (HRV) reflects autonomic regulation and is widely used in cardiovascular monitoring. Photoplethysmography (PPG) is commonly used for continuous heart rate ...

Background Heart rate variability (HRV) parameters are an important indicator of cardiovascular health. While it has been well established that aerobic exercise improves HRV, the effects of resistance ...

Something fascinating happens every time we interact with another person in a meaningful way: Several of our biological signals start to synchronize. This has been shown for various brain waves and ...

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 ...

Real-time and early detection of minute changes in the functioning of the cardiovascular system is crucial for managing critically ill patients, such as newborns and older adults, and can ...

It might be time to start listening to your heart. In recent years, millions of Americans have incorporated wearable health trackers like smartwatches and Oura rings into their lives, with studies ...

Heart rate variability (HRV), the variation in intervals between consecutive heartbeats, reflects autonomic nervous system function and has been studied as a potential biomarker in cardiovascular ...

Fitness trackers and smart watches are widely popular wearable devices that measure several types of health metrics, including step count, calories burned, sleep quality, Vo2 max and heart rate. As a ...

Modern smart watches can measure all sorts of health indicators. Step counts and heart rates sit at the simpler end of the array, whereas VO 2 max and blood-oxygen levels are of more interest to ...
