Estimation of exercise intensity using heart rate during sleep

Dynamic Modelling of Heart Rate Response Under Different Exercise Intensity

Heart rate is one of the major indications of human cardiovascular response to exercises. This study investigates human heart rate response dynamics to moderate exercise. A healthy male subject has been asked to walk on a motorised treadmill under a predefined exercise protocol. ECG, body movements, and oxygen saturation (SpO2) have been reliably monitored and recorded by using non-invasive por...

Heart rate variability during nap sleep.

Benzodiazepine hypnotics increase heart rate during sleep.

The cardiovascular effects of benzodiazepines administered intravenously as preoperative sedatives have received considerable study, but sleep laboratory research on benzodiazepines administered orally as hypnotics has not focused on assessment of cardiovascular changes. Analysis of heart rate (HR) data collected in sleep laboratory studies on the effects of 0.5 mg of triazolam (Halcion) and 30...

Heart Rate Variability During Physical Exercise

Heart rate variability (HRV) is the present oscillation of the heart rate. The interest in HRV as a parameter of the parasympathetic and sympathetic influence of the autonomic nervous system on the heart has increased in the last few decades (Kaikkonen et al., 2007). It is known that its influence changes under different conditions such as rest, exercise or mental stress and different body post...

The Heart Rate during a Simple Exercise.

Simple exercise tolerance tests, such as stepping on and off a stool a given number of times and noting the effect on the pulse rate, have long been used in medical practice. Almost invariably, however, the pulse rate is taken before and after, owing to the difficulty of counting it during the exercise. This may be overcome by means of a recording apparatus such as that of Bell and Knox (1938);...
