The purpose of this study was to observe the effect of high intermittent exercise training on children’s heart rate variability (HRV). Thirty-eight children (age 9.6 ± 2 years) were divided into an intermittent (IT, n = 22) and a control group (CON, n = 16). At baseline and after...
Objective To analyze the effect of high temperature on heart rate variability and the nervous modulation mechanism by collecting electrocardiogram of isolated heart in the toads at two different temperatures. Methods Prepared the isolated heart perfusion specimen ,then connected the specimen to water incub...

Subjects with baseline heart rates less than 70 bpm and subjects with baseline heart rates greater than or equal to 70 bpm were assigned to low heart rate and high heart rate groups, respectively. The primary outcome of this analysis was a composite of death from cardiovascular causes, aborted...

involving patients in septic shock with a heart rate of 95/min or higher requiring high-dose norepinephrine to maintain a mean arterial pressure of 65 mm Hg or higher.INTERVENTIONS We randomly assigned 77 patients to receive a continuous infusion of esmolol titrated to maintain heart rate between...
High attachment anxiety is reliably associated with adverse health outcomes, whereas high attachment avoidance is associated with adverse health outcomes when co-occurring with poor self-regulatory capacity, indexed by heart rate variability (HRV). We examined the associations between attachment anxiety, ...
To test the generality, across modality and across species, of a bidirectional effect of photic stimulation in infant rats found in previous experiments, two experiments examined the effects on heart rate (HR) of onset and offset of auditory stimulation in rats and of photic stimulation in guinea...
To remove the potential confounder of medication, this study included patients with de novo Parkinson disease.19 The study examined whether patients with de novo Parkinson disease can consistently and safely exercise on a treadmill at high intensity (80%-85% maximum heart rate) or moderate ...
