VO2 max testing requires intense exercise that raises your heart rate extremely high to fully stress the body to its limits. You should always perform the test under the supervision of a trained medical or fitness professional, but especially if you have any existing health concerns with your he...
In this trial, we randomly assigned patients to pacing programmed to a base rate of 60 bpm with rate-adaptive pacing (DDDR-60) or pacing programmed to a base rate of 40 bpm without rate-adaptive pacing (DDD-40)...
Orthostatic heart rate (HR) signals have received less attention. We studied the association between beat-to-beat orthostatic hemodynamic variables in TILDA wave 1 (2010) and incident mortality in wave 2 (2012).Methods: Of the 8175 participants aged 50 and over in the first wave of TILDA, ...
Heart rate research in psychology and medicine Heart rate (HR) has long been used as a clinical indicator of overall cardiac health. HR is predominantly influenced by the coordination of the sympathetic and parasympathetic branches of the autonomic nervous system, which can be modified by ...
Low heart rate variability (HRV) has been proposed as a marker of a number of pathophysiologic conditions, including increased risk of mortality 1, 2, 3, 4, 5, 6. Cutpoints for increased risk of mortality also have been proposed 2, 3, 7. However, the use of HRV for predictive purposes...
