Disease relevance of Atrial Function

• This study determined the effect of sotalol on atrial function after electrical cardioversion of atrial fibrillation [1].
• Two hundred micromolar P1,P5-di(adenosine-5')pentaphosphate (Ap5A) stopped atrial function in less than 30 s of anoxia in contrast to 50 s in the case of Hearse's cardioplegic solution (16 mM MgCl2, 16 mM KCl, 1 mM Procaine), and 20 min in the case of controls [2].
• Dilated cardiomyopathy in Friedreich's ataxia: 2D echo and tissue-Doppler analysis of left ventricular and atrial function [3].

High impact information on Atrial Function

• Warfarin should be continued for 1 month after cardioversion to allow for more complete recovery of atrial function and for prophylaxis should the patient revert to AF [4].
• Neither NNA nor aminoguanidine reversed the depression in atrial function [5].
• Prucalopride is a gastrointestinal prokinetic drug that acts through 5-HT4 receptors, but its potential effects on cardiac atrial function are unknown [6].
• The pure class III agent dofetilide was evaluated to determine its effect on atrial function after cardioversion of atrial fibrillation or flutter [7].
• SR imaging indexes could provide new, noninvasive, clinically relevant insight on regional changes in atrial function for patients with ASD [8].

Chemical compound and disease context of Atrial Function

• Preserved atrial response to dobutamine stress after the modified maze procedure for chronic atrial fibrillation: echocardiographic assessment of atrial function [9].

Biological context of Atrial Function

• 4 weeks after STZ, atrial function was found to be depressed, whereas right ventricular function was enhanced [10].

Associations of Atrial Function with chemical compounds

• We postulated that after cardioversion, when intrinsic atrial function is impaired, sotalol may have an adverse effect on the atrium [1].
• Treatment of diabetic rats with the ARI sorbinil was successful in preventing only one of the observed diabetes-induced changes in atrial function, namely the supersensitivity of left atria to isoprenaline [11].
• These data suggest that the endogenous-TG and glucose share in supporting the atrial functions, that insulin is involved in the control of TG consumption only in the fed state and that the greater TG mobilization in the fasted atria, at least partly, meets the energy requirements of the tissue [12].
• The aim of the investigation was to assess whether endogenous triacylglycerol contributes to the maintenance of the atrial functions [13].
• Inasmuch lactate output did not change and these effects manifested only in the atria predisposed to the utilization of endogenous lipids, it may be inferred that oxfenicine preserved the atrial functions through the inhibition of fatty acid oxidation [14].

Gene context of Atrial Function

• Effects of systolic atrial function on plasma renin activity and natriuretic peptide secretion after high rate atrial and ventricular pacing in dogs [15].
• 4. Glibenclamide (0.1 microM), a selective K+ATP channel blocker, did not improve the hypoxia-induced depression of atrial function [16].
• These findings indicate that subjects in SR exhibited less impaired atrial function which were evaluated by exercise testing with measurement of ANP, echocardiography, and cardiac catheterization [17].
