The influence of epidural anesthesia on the electrical activity of heart atria. [PDF]
Kardiochir Torakochirurgia Pol, 2014 High thoracic epidural anesthesia (TEA) causes blockade of sympathetic fibers involved in innervation of the heart (segments T1-T4), which results in changes of cardiac electrophysiology. The anti-arrhythmic effects of TEA on supraventricular arrhythmias, mainly atrial fibrillation, are controversial.The aim of the study was to assess the influence of ...

Twin heart with a fused atria and separate ventricles in conjoined twins
Annals of Pediatric Cardiology, 2010 One of the most interesting congenital malformations is that of conjoined twins. We report echocardiographic features of twin heart in dicephalus, tribrachius, dispinous, thoracoomphalopagus twin. It showed two hearts fused at atrial level.

Trandolapril Attenuates Pro-Arrhythmic Downregulation of Cx43 and Cx40 in Atria of Volume Overloaded Hypertensive and Normotensive Rats [PDF]
BiomoleculesPressure overload in non-treated or resistant hypertension (HTN) increases the risk of heart failure (HF) as well as the occurrence of fatal ventricular arrhythmias and stroke-provoking atrial fibrillation (AF), while perturbed connexin-43 (Cx43) and ...

Transgenic mice overexpressing Pitx2 in the atria develop tachycardia-bradycardia syndrome. [PDF]
PLoS ONESinoatrial node (SAN) dysfunction often accompanies supraventricular tachyarrhythmias such as atrial fibrillation (AF), which is referred to as tachycardia-bradycardia syndrome (TBS). Although there have been many studies on electrical remodeling in TBS,

Participation of G Proteins in Natriuretic Peptide Hormone Secretion from Heart Atria [PDF]
Endocrinology, 2004 The involvement of G proteins in the mechanism underlying the increased atrial natriuretic factor (ANF) secretion observed after atrial muscle stretch (stretch-secretion coupling) was assessed using a combined pharmacological, immunocytochemical, and tissue fractionation approach.

Functional and Structural Differences in Atria Versus Ventricles in Teleost Hearts
, 2012 Across vertebrates, the fish heart is structurally relatively simple. The heart of teleosts is unique in structure, composed of four chambers in series: venous sinus, atrium, ventricle and bulbus arteriosus. The two chambers acting as pumps are the atrium and ventricle, a simplified ver‐ sion of that seen in tetrapods.
