Estimation of age and gender peculiarities of heart rate variability (HRV) in adolescents will help researchers to predict the potential abilities of the adaptation mechanisms, to evaluate the risk of cardiovascular diseases, and to select the dosage of physical activity in sporting and rehabilitation ...
Heart rate variability (HRV) denotes the time interval between consecutive heartbeats.The HRV signal, as detected by the sensors and devices, has been popularly used as an indicative measure to estimate the level of stress, depression, and anxiety. For years, artificial intelligence (AI)-based ...
9,10,11,12,13,14,15. For the majority of the clustering solutions, the duration of the preictal interval ranged from approximately 2 to 9 min. The results also show the high variability of this interval both between and within patients, reinforcing the need for patient-specific approaches in...
The coefficient of variation detects the amount of IBI variability relative to the mean IBI of each subject, and deals with the proportionality-based dependence of HRV on heart rate19. Second, we established the effect of the 17 HRV SNPs on the coefficients of variation for SDNN and RMSSD in...
Power-law relationship of heart rate variability in worsening heart failure and its age-dependence 来自 ResearchGate 喜欢 0 阅读量: 20 作者:H Schmidt,K Knies,S Abromeit,P Tymiec,M Rauchhaus 摘要: A basic feature of the healthy human body is a continuous communication between all vital organs...
To derive the power-law relationship, the frequency-domain data are plotted [log(power) versus log(frequency)], and the inverse slope of this plot helps to define the complexity of heart rate fluctuations. The complexity of variability analyzed by nonlinear methods can also be expressed with ...
For a definition to be also useful for the nonspecialist, it should be assessable easily and with relatively low interobserver variability. The Framingham criteria, which were developed for just such a purpose,23 are now considered insufficiently specific for adoption as a definition of HF in the...
The effect of workplace smoking bans on heart rate variability and pulse wave velocity of non-smoking hospitality workers Objectives To investigate the effect of a change in second-hand smoke (SHS) exposure on heart rate variability (HRV) and pulse wave velocity (PWV), this st... S Rajkumar...
Heart rate variability (HRV) is a reliable reflection of the many physiological factors modulating the normal rhythm of the heart. In fact, they provide a powerful means of observing the interplay between the sympathetic and parasympathetic nervous systems. It shows that the structure generating the...
