Test-retest reproducibility of heart rate recovery after treadmill exercise.
BACKGROUND Slowed heart rate recovery (HRR) of less than 12 beats per minute in the first minute after an exercise stress test has been suggested as a useful addition to the criteria currently used to assess exercise stress test results. Although HRR has been tested in large populations, the short-term test-retest stability (reproducibility) of abnormal HRR for an individual has not been assess...
متن کاملReliability of Lagged Poincaré Plot parameters in ultra-short Heart Rate Variability series: Application on Affective Sounds.
The number of studies about ultra-short cardiovascular time series is increasing because of the demand for mobile applications in telemedicine and e-health monitoring. However, the current literature still needs a proper validation of heartbeat nonlinear dynamics assessment from ultra-short time series. This paper reports on the reliability of the Lagged Poincaré Plot (LPP) parameters - calcula...
متن کاملInformative Nature and Nonlinearity of Lagged Poincaré Plots Indices in Analysis of Heart Rate Variability
Lagged Poincaré plots have been successful in characterizing abnormal cardiac function. However, the current research practices do not favour any specific lag of Poincaré plots, thus complicating the comparison of results of different researchers in their analysis of heart rate of healthy subjects and patients. We researched the informative nature of lagged Poincaré plots in different states of...
متن کاملPower spectral and Poincaré plot characteristics in sinus node dysfunction.
A salient feature of the normal sinus node activity is its prominent beat-to-beat variability, which shows self-similarity on different time scales (fractal dynamics). However, in patients with sinus node dysfunction, short-term time sinus cycles show exaggerated variability, the characteristics of which have not been analyzed. Therefore, Poincaré plots and power spectral analysis were applied ...
متن کاملDecrease in heart rate variability with overtraining: assessment by the Poincaré plot analysis.
Numerous symptoms have been associated with the overtraining syndrome (OT), including changes in autonomic function. Heart rate variability (HRV) provides non-invasive data about the autonomic regulation of heart rate in real-life conditions. The aims of the study were to: (i) characterize the HRV profile of seven athletes (OA) diagnosed as suffering of OT, compared with eight healthy sedentary...
