It has been demonstrated that heart rate variability (HRV) is predictive of all-cause and
cardiovascular mortality using clinical ECG recordings. This is true for rest, exercise and …

Heart rate variability (HRV), the beat-to-beat variation in either heart rate or the duration of
the RR interval, has become a popular clinical and investigational tool (Task Force of the …

The aim of this study was to investigate the training-induced effect on cardiac
parasympathetic nervous system (PNS) activity, assessed by resting heart rate variability …

Spexin is a novel neuropeptide playing an emerging role in metabolic diseases such as
obesity and diabetes via involvement in energy homeostasis and food intake. The present …

Background: Preoperative assessment is crucial to prevent the risk of complications of
surgical operations and is usually focused on functional capacity. The increasing availability …

The associations between cardiovascular disease (CVD) risk factors and heart rate
variability (HRV) have shown some inconsistencies. To examine the impact of the different …

Background: Heart rate variability (HRV) is primarily heart rate (HR) dependent, and
therefore, different HR may exert different impact on HRV. The objectives of the study were …

Background There is no evidence of the use of beetroot juice with a previously
recommended dose of nitrate (NO3)(> 300 mg) on the cardiovascular performance during …

Low values on heart rate variability (HRV) derived parameters at resting have been used to
predict cardiovascular diseases (CVD) and mortality. In this regard, short-term HRV …

Cardiac autonomic neuropathy resulting from human immunodeficiency virus (HIV) infection
is common; however, its mechanism remains unknown. The current work attempted to …
