The Heart rate variability (HRV) is a non-invasive index of the neural control of the heart. HRV can be quantified by the simple calculation of the standard deviation of the R-R intervals. Furthermore, in the frequency domain, spectral analysis of HRV reveals three distinct frequency regions ...
The reproducibility of the heart rate response to the Valsalva manoeuvre was assessed in 12 young normal subjects who each repeated the manoeuvre 10 times. The length of the RR intervals before, during, and after each Valsalva manoeuvre was measured from an electrocardiogram and the changes expresse...

Morphologically normal heart Sex Atria Ventricles Valves Sub-epicardial fat 1. Introduction Sudden cardiac death (SCD) is a leading cause of mortality, accounting for around half of all deaths from cardiovascular disease and the majority are due to coronary artery disease [1]. Sudden adult death ...
Plug in the cardiac output and the heart rate and solve for the stroke volume using simple Algebra. What is normal cardiac output? In an adult at rest, the normal cardiac output ranges from 5-6 Liters per minute. This increases with exercise to much higher numbers so it is important the...

Reasons for high Heart Rate in Sports Pulse rate too low When an adult’s pulse rate is less than 50 to 60 beats per minute (bpm), it is called bradycardia. For children, other limits apply depending on their age.16 However, as a population-based cohort study published in 2016 suggests...
