We evaluated age- and sex-dependent differences in heart rate variability (HRV) during the 6-min walk test (6MWT) in healthy adults. We also evaluated the intensity of the 6MWT based on HRV. 78 participants aged 40–49, 50–59, 60–69, and ≥70 years (42 females; 36 men) performed...
On standard electrocardiogram (ECG) PQ interval is known to be moderately heart rate dependent, but no physiologic details of this dependency have been established. At the same time, PQ dynamics is a clear candidate for non-invasive assessment of atrial
High Heart Rate: A Risk Factor for Cardiovascular Death in Elderly Men To examine the association between heart rate and 12-year incidence rates of total and cardiovascular death in a cohort of elderly subjects stratified by sex.The study was carried out in 763 white men and 1175 women aged ...
Heart rate variability and heart rate in healthy volunteers. Is the female autonomic nervous system cardioprotective? Eur. Heart J. 19, 1334–1341 (1998). Article CAS Google Scholar Murphy, E., Amanakis, G., Fillmore, N., Parks, R. J. & Sun, J. Sex differences in metabolic ...
The article presents the results of a study which investigated the relationship between strength training intensity and heart rate variability (HRV) in older men. An overview of related previous research is provided, along with details of the experimental protocol. It was found that HRV correlated ...
ECGs selected for analysis were normal, recorded in regions north of the equator, and taken on subjects ≥18 years old. The QT correction for heart rate (HR) was performed using QTc = QT*(HR/60) 0.4. The monthly mean QTc intervals were compared, for men and women separately, using a ...
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...
Multiple investigators have confirmed that abnormal HRR, defined as failure of heart rate to decrease 12 beats or more during the first minute after peak exercise (while the patient remains standing) independently predicts an increased mortality in men and women [70,89]. Further, the greater the...
To study the relationship between heart rate and (a) all deaths and (b) cardiovascular deaths in a large cohort of middle-aged Norwegian men and women.A prospective study of participants in cardiovascular surveys that were carried out in 1985-1999 and covered men and women aged 40-45 years ...
What’s normal depends on your age and activity level but, generally, a resting heart rate of 60 to 80 beats per minute (BPM) is considered to be in the normal range. If you are an athlete, a normal resting heart rate can be as low as 40 BPM. Studies have shown that men tend ...
