Enkephalin effects on blood pressure, heart rate, and baroreceptor reflex.
The cardiovascular effects of opioid peptides have been studied. Leucine-enkephalin (Leu-ENK) produced blood pressure (BP) increases following administration into the lateral brain ventricles (i.v.t.), into the cisterna magna (i.c.i.), and following intravenous (i.v.) administration. Heart rate (HR) increases were observed following all routes of administration (threshold for BP and HR effects ...
متن کاملEffects of work stress on ambulatory blood pressure, heart rate, and heart rate variability.
Work stress has repeatedly been associated with an increased risk for cardiovascular disease. This study tested whether this relationship could be explained by exaggerated cardiovascular reactivity to work or impaired recovery in leisure time. Vagal tone was assessed as a possible determinant of these work stress effects. Participants included 109 male white-collar workers (age, 47.2+/-5. 3) wh...

15 صفحه اولPhase Synchronization analysis of Heart Rate Variability and Systolic Blood Pressure Variability under Postural Stress
In this paper, the coupling between heart rate variability (HRV) and systolic blood pressure variability is analyzed using a non-linear measure called phase synchronization index (PSI). 20 healthy subjects alongwith 20 post myocardial patients undergong postural stress were used for analysis. The results were validated on standard EuroBaVar dataset. Results demonstrate that i) for healthy subje...
