Bradycardia is a slow heart rate -- fewer than 60 bpm. Your resting heart rate typically drops below 60 bpm when you're sleeping. Some athletes and young adults can have heart rates of 40-60 bpm as well. More seriously, bradycardia results from your heart being unable to pump well enough...
The impact of birth weight (BW) on adult health has been studied, related to the autonomic nervous system, and implicated in cardiovascular risk. We investigated cardiorespiratory and heart rate (HR) autonomic recovery after moderate effort in healthy term-born adults with different BWs. We studied...
While there is no resting heart rate difference by age, your target heart rate can vary. Target heart rate is a range that shows how fast your heart should be beating when you're exercising. It's considered an ideal zone for getting the most out of your workout without overworking. ...
During dynamic exercise, it is generally assumed that heart rate increases due to both a parasympathetic withdrawal and an augmented sympathetic activity. However, because some authors disagree with the former statement and the fact that during exercise there is also a technical problem related to the...
Heart rate (HR) and heart rate variability (HRV) are commonly used physiological parameters in animals. While HR indicates the average number of heartbeats per minute, HRV corresponds to the fluctuation in the inter-beat intervals (IBIs) and is deemed a finer measure of the functioning of the...
Pacemaker.A pacemaker is a small device that controls your heartbeat. Your doctor inserts the device under the skin on your chest, then hooks it up to your heart with tiny wires. The device steadies your heart rate when it beats too slowly. ...
Wearables are being increasingly used to monitor heart rate (HR). However, their usefulness for analyzing continuous HR in research or at clinical level is questionable. The aim of this study is to analyze the level of agreement between different wearables in the measurement of HR based on photo...
As you age, your heart may not be able to beat as fast during times of physical activity or stress as it did when you are younger. Your resting heart rate, however, should not change significantly with normal aging. What is a Dangerous Heart Rate? There are two types of dangerous heart...
Furthermore, these ANS responses are initiated at different times after the change in the various environmental factors and continue over different lengths of time. Solar wind was negatively correlated with IBIs indicating that heart rate increases with increases in solar wind that suggests a ...
Heart rate variability (HRV) is often used as an index of emotion regulation response. Hence, our goal is to investigate whether the habitual use of coping strategies is related to a distinct pattern of HRV changes when the individual is exposed to a moderate psychosocial stressor. In this ...
