INFARCTION(IHD)Objective Resting heart rate (RHR) is an established predictor of myocardial infarction (MI) and mortality, but the relationship between variation in RHR over a period of several years and health outcomes is unclear. We evaluated the relationship between long-term variation in RHR ...
CONCLUSION: A decrease in the resting and submaximal heart rate is the earliest effect of increased physical activity. Familiarization to exercise protocol ... A. W. ZIEMBA,J. CHWALBINSKA-MONETA,H. KACIUBA-USCILKO,... - 《Journal of Sports Medicine & Physical Fitness》 被引量: 41发表: 20...
changes in heart rate or investigated cardiorespiratory variation during cardiac awareness tasks. Cardiorespiratory dynamics refer to the acknowledged influence of breathing on heart rate and blood pressure, and vice versa31. This influence is most readily apparent in the case of the effect of breathing...

Remote photoplethysmography (rPPG) gains recent great interest due to its potential in contactless heart rate measurement using consumer-level cameras. This paper presents a detailed review of rPPG measurement using computer vision and deep learning techniques for heart rate estimation. Several common gaps...
Our heart-rate monitors were adapted from Giese et al.79, who found that resting heart rate of Adélie penguins recorded using artificial eggs were indistinguishable from those recorded using electrocardiogram units attached externally to the penguins (Fig. 4; see Geldart et al. in review for ...

195 Th17 lineage specification also requires polyamine metabolism because inhibition of the rate-limiting enzyme ornithine decarboxylase 1, which converts arginine to ornithine, blocks Th17 induction and favors Treg polarization.196 In the Framingham Heart Study, ornithine was the top metabolite associated...
Reduced heart rate (HR) during vagus nerve stimulation (VNS) is associated with therapy for heart failure, but stimulation frequency and amplitude are limited by patient tolerance. An understanding of physiological responses to parameter adjustments would allow differential control of therapeutic and side...
