Periodic variation in R-R intervals and cardiovascular autonomic regulation in young adult Syrian hamsters.
Several hamster strains are commonly used as models for cardiomyopathic phenotypes evolving toward heart failure. However, little is known about heart rate variability (HRV) in this species. Prolonged surface ECG recording, a prerequisite to HRV studies, can be obtained either by telemetry or by restraints. Here, we performed long time ECG recording using telemetry on young adult Syrian hamster...

Effect of salt-loading on blood pressure, insulin sensitivity and limb blood flow in normal subjects.
1. The aim of this study was to determine the effects of high (220 mmol/day) and low (40 mmol/day) salt intake for 6 days on blood pressure, leg blood flow and insulin sensitivity in 18 healthy normotensive subjects. 2. Twenty-four-hour ambulatory blood pressure was measured at baseline, during salt-loading and salt-depletion. Insulin sensitivity was determined by a two-step euglycaemic-hyperin...
متن کاملEffects of systemic hypoxia on R-R interval and blood pressure variabilities in conscious rats.
The effects of systemic hypoxia with different levels of CO2 on R-R interval (RRI) and systolic blood pressure (SBP) variabilities were investigated in conscious rats. Wistar rats chronically instrumented for the measurement of blood pressure, electrocardiogram, and renal sympathetic nerve activity (RSNA) were exposed to hypocapnic (Hypo), isocapnic (Iso), and hypercapnic (Hyper) hypoxia. On an...
