23,24. Resting heart rate is defined as the number of beats per minute when the individual is at complete rest. It indicates the basic fitness level, therefore, the more well-conditioned the body, the less effort and
Heart rate variability was defined as the standard deviation of normal-to-normal RR intervals (SDNN). Functional status in basic (ADL) and instrumental (IADL) activities of daily living was measured using Barthel and Lawton scales, at baseline and during follow-up.The mean age of the study ...

The study also highlighted that an individual’s resting heart rate is pretty much consistent over time, and so deviations from the typical rate could be an important sign that something is wrong. “The variability of the resting heart rate may provide additional information, not only for cardiov...
Cardiovascular risk and risk reduction were analyzed in five subgroups defined by quintiles (Q) of pretreatment resting HR in the Metoprolol Controlled Release/Extended Release Randomized Intervention Trial in Chronic Heart Failure (MERIT-HF). Mean baseline HR in the 5 Qs were 71, 76, 81, 87, ...
To track blood pressure (BP) and resting heart rate (RHR) in children and adolescents is important due to its associations with cardiovascular outcomes in the adulthood. Therefore, the aim of this study was to examine BP and RHR over a decade among child
The researchers defined high resting heart rate as greater than or equal to 83 beats per minute and low resting heart rate as less than or equal to 60 beats per minute. The results showed that compared to the 139,511 men with the highest restingheart rate, the 132, 595 men with the lo...
These findings remained consistent in analyses accounting for incident coronary heart disease, excluding individuals with prior cardiovascular events, or those taking beta‐blockers; and in subgroups defined by several individual participant characteristics. In a pooled random effects meta‐analysis of 7...
Before heart rate (HR) variability can be used for predictive purposes in the clinical setting, day-to-day variation and reproducibility need to be defined... DV Hoogenhuyze,N Weinstein,GJ Martin,... - 《American Journal of Cardiology》 被引量: 376发表: 1991年 Intraindividual Reproducibility ...
Pre-defined endpoints were disability after a recurrent stroke, assessed with the modified Rankin scale (mRS) and the Barthel index at 3 months, and cognitive function, assessed with the Mini-Mental State Examination (MMSE) score at 4 weeks after randomization and at the penultimate visit. ...
