In no case was the maximal heart rate higher when breathing O2 than when breathing air. This low maximal heart rate in older people probably limits the capacity for O2 intake. Four subjects were able to work for about 1 hour without any sign of exhaustion on a work load requiring an O2 ...
Heart Rate:Heart rate refers to the number of times the heart contracts (i.e., beats) each minute. A normal heart rate is considered to be between 60 to 100 beats per minute. Tachycardia refers to a heart rate faster than normal, and bradycardia refers to a heart rate slower than ...
5a). However, the decay rate of \(E_{B}(t_{MF}(\textrm{epoch}))\) curves for the shuffled RRi series was comparable to that of the original RRi series in the narrow range of 20 epochs (\(E_{B}(t_{MF}(\textrm{epoch}))=-1.2091\frac{\Delta }{\textrm{epoch}},-1.1555\frac...
Patrick is a 70-year-old diabetic man with a 2-year history of stable chest pain when he exerts himself. He is awoken from sleep with the acute onset of crushing central chest pain which radiates to his neck and left arm. His normal medications include normally aspirin, a diuretic, a ch...

On the other hand, the cascade-dynamical descriptors, the Hurst exponent encoding linear temporal correlations, and multifractal nonlinearity encoding nonlinear interactions across scales described the nonergodic heart rate variability more ergodically and were specific. This study inaugurates applying the ...
