Abnormal Response of Superior Sinoatrial Node to Sympathetic Stimulation Is a Characteristic Finding in Patients With Atrial Fibrillation and Symptomatic Bradycardia Running title: Joung et al.; Superior Sinoatrial Node Dysfunction in AF
Background We hypothesize that unresponsiveness of superior sinoatrial node (SAN) to sympathetic stimulation is strongly associated with the development of symptomatic bradycardia in patients with atrial fibrillation (AF). Methods and Results We performed 3-dimensional endocardial mapping in healthy control (Group 1, n=10) and in patients with AF without (Group 2, n=57) or with (Group 3, n=15) ...

متن کاملInhibition of epinephrine-induced lipolysis in isolated white adipocytes of aging rabbits by increased alpha-adrenergic responsiveness.
The aim of this study was to explain the unresponsiveness of rabbit perirenal adipose tissue to epinephrine. The in vitro lipolytic response to isoproterenol and to epinephrine alone or associated with alpha- or beta-adrenergic blocking agents, was studied in the adipocytes of rabbits of various ages. Epinephrine induces a large glycerol release in young rabbit adipocytes whereas an increase in...
متن کاملthe effect of isoproterenol on protein electrophoretic pattern of rabbit salivary Glands
Isoproterenol is a potent B-adrenergic agonist which its effect on rabbit salivary Glands has been studied in this research.two groups of male albino rabbits(five in each group with the mean weight of 1000+_300 gr) were injected with 20 mg/kg of isoproterenol intrapritoneally each day for fifteen days and one similar group(n=5) was chosen as control group.in one of the test groups in addition ...
متن کاملCardioprotective Effects of Essential Oil of Lavandula angustifolia on Isoproterenol-induced Acute Myocardial Infarction in Rat
Myocardial infarction (MI) is a common presentation of the ischemic heart disease. Lavandula angustifolia is a herbaceous plant with antioxidative effects.This study was designed to investigate the cardioprotective effects of lavandula angustifolia essential oil against isoproterenol-induced MI in rats.The dried sample was subjected to hydrodistillation by using a Clevenger and the oils were dr...
