BACKGROUND Whether heart rate upon discharge following hospitalization for heart failure is associated with long-term adverse outcomes and whether this association differs between patients with sinus rhythm (SR) and atrial fibrillation (AF) have not been well studied. METHODS AND RESULTS We conducted a retrospective cohort study from clinical registry data linked to Medicare claims for 46 217...

in order to investigate the combined effects of shift work and heat stress on the physiological parameters, such as heart rate (hr) and body temperature (bt), a hot-dry working environment was investigated for 53 workers in foundry workshops. in this study wet bulb globe temperature index (wbgt) was measured and along with that simultaneously heart rate and oral temperature were checked in 3 sh...

conclusions propofol provided a safe and acceptable sedation for post-cabg surgical patients, significantly reduced the requirement for analgesics, and allowed for more rapid tracheal extubation than midazolam but did not result in earlier icu discharge. results the depth of sedation was almost the same in the two groups (rss=4.5 in midazolam group vs 4.7 in propofol group; p = 0.259) but the t...

Heart-rate variability (HRV), measured by the fluctuation of beat-to-beat intervals, has been growingly considered most important hallmark heart rate (HR) time series. The HRV can be characterized various statistical measures both in and frequency domains, or nonlinear methods. During past decades, an overwhelming amount data piled up research community, but individual results are difficult to ...

IT IS WELL KNOWN THAT ATHLETES have a low resting heart rate, i.e., a resting bradycardia and heart rates below 30 beats/min have been reported (7). For example, Wikipedia states that the Tour de France cyclist, Miguel Indurain, had a resting heart rate of 28 beats/min when race fit. The resting bradycardia in athletes is most often attributed to high vagal tone, i.e., high parasympathetic nerv...

A group of seven male participants [aged 22,9 (SD = 0,9) years] twice performed, a two-leg extension effort lasting a total of 4 minutes with a 30% intensity of maximal voluntary contraction (MVC), in the sitting (ST) and two days later in the supine position (SU). At rest, during each minute of exercise and the 4 minute recovery period the following variables were measured: heart rate (HR), st...
