Blood pressure and heart rate variabilities were studied in 89 ambulant normotensive or essential hypertensive subjects in whom blood pressure was recorded intra-arterially for 24 hours (Oxford method) under standardized living conditions. Data were analyzed beat to beat by a computer to provide mean values of the 48 half hours of the 24-hour period. Variabilities were assessed by the standard ...

background: systolic blood pressure recovery (rsbp) is of prognostic value for predicting the survival and co-morbidity rate in patients with coronary artery disease (cad). this study investigated the association between rsbp and exercise indices after complete cardiac rehabilitation program (cr) in a population-based sample of patients undergoing coronary artery bypass grafting (cabg). methods...

Bombesin-like receptor 3 (BRS-3) is an orphan G protein-coupled receptor that regulates energy expenditure, food intake, and body weight. We examined the effects of BRS-3 deletion and activation on blood pressure and heart rate. In free-living, telemetered Brs3 null mice the resting heart rate was 10% lower than wild-type controls, while the resting mean arterial pressure was unchanged. During ...

Background: The virtual rise of blood pressure resulted from stress, that is observed in subjects that are tested in medical centers, can be oftenly corrected by holter. This phenomenon causes such persons not to response to the common anti blood pressure treatments (2). Materials and methods: This descriptive study was conducted 2006-2007 at the heart clinic of Shohadaye–Ashayer hospital in Kh...

To evaluate the impact of electroconvulsive therapy on arterial blood pressure, heart rate, heart rate variability, and the occurrence of ischemia or arrhythmias, 38 (18 men) depressive patients free from systemic diseases, 50 to 83 years old (mean: 64.7 +/- 8.6) underwent electroconvulsive therapy. All patients were studied with simultaneous 24-h ambulatory blood pressure and Holter monitoring...

Background: Cataract is one of the most common eye diseases especially in children and adolescents in two age ranges, and many of these patients need to surgery throughout life. The purpose of this study was to compare the efficacy and side effects of midazolam-ketamine and midazolam-fentanyl for sedation in adult cataract surgery. Methods: In this study, which was a case-control study, 80 pat...
