Analysis of twenty-four hour heart rate variability in patients with panic disorder.
Growing evidence suggests that alterations in autonomic function contribute to the pathophysiology of panic disorder (PD). This retrospective study employed 24-h heart rate variability (HRV) analysis of Holter records to compare autonomic function in PD patients (n = 38) with healthy, age- and gender-matched controls. Both time and frequency domain measures were calculated, and a circadian rhyt...
متن کاملTwenty-four-hour blood pressure and heart rate profiles in humans. A twin study.
To delineate the relative roles of genetic and environmental factors on physiological variations of blood pressure and heart rate, we performed 24-hour ambulatory blood pressure monitorings with simultaneous polygraphic sleep recordings in 28 monozygotic and 16 dizygotic healthy young male twin pairs investigated in a standardized physical and social environment. Blood pressure and heart rate w...
متن کاملTwenty-Four Hour Non-Invasive Ambulatory Blood Pressure and Heart Rate Monitoring in Parkinson’s Disease
Non-motor symptoms are now commonly recognized in Parkinson's disease (PD) and can include dysautonomia. Impairment of cardiovascular autonomic function can occur at any stage of PD but is typically prevalent in advanced stages or related to (anti-Parkinsonian) drugs and can result in atypical blood pressure (BP) readings and related symptoms such as orthostatic hypotension (OH) and supine hype...
متن کاملTwenty-four hour simulation of solar chimneys
A model for time dependent analysis of solar chimneys is presented. The energy balance equations for three components of solar chimneys, absorbing plate, cover glass and air-gap are discretized with respect to time using an implicit finite difference model. The discretized nonlinear energy balance equations are solved for numerous time steps over a 24-h period using the Newton–Raphson method. T...
متن کاملTwenty-four hour efficacy of glaucoma medications.
Current medical therapy of glaucoma aims to attain a meaningful and consistent reduction of intraocular pressure (IOP) to a predetermined level of target IOP, which will commensurate with either stability, or delayed progression of visual loss. Glaucoma is a 24-h disease and the damaging effect of elevated IOP is continuous. Therefore, it is reasonable that we should endeavor to identify the tr...
