Electrolyte Content of Rat Heart Atria and Ventricles [PDF]
Circulation Research, 1960 Extracellular tissue spaces are compared using inulin, sucrose, chloride and sodium in hearts perfused with Ringer-Locke solution by Langendorff's method. Also chloride and sodium spaces are given for unperfused, fresh hearts. From the inulin spaces the intracellular chloride, sodium, potassium and water concentrations in both perfused and unperfused ...

Vasoactive Intestinal Polypeptide in Rat Heart Atria: the Effect of Hyperthyroidism
Physiological Research, 2000 The effects of transient and sustained hyperthyroidism on vasoactive intestinal polypeptide-like immunoreactivity (VIP-LI) levels were studied in the heart atria of developing and adult rats. Newborn rats were divided into 5 groups.

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 ...

Observations on the Atria of the Human Heart by Direct and Semidirect Electrocardiography [PDF]
Circulation, 1952 By evaluation of direct electrocardiographic leads from the right atrium and semidirect esophageal leads from the left atrium, "atriodiagrams" have been constructed for both atria. The spread of activation in the atria has been studied under normal conditions as well as in cases of mitral heart disease, cor pulmonale, etc.

Ischemic heart disease: structural changes of the atria in preinfarction and postinfarction stages [PDF]
Medicina, 2007 Objective. The aim of this study was to determine atrial structural remodeling during the development of ischemic heart disease. Material and methods. Quantitative histomorphometric parameters of interstitial collagen network (the percentage volume, perimeter, number of fibers per field and collagen–cardiomyocyte volume ratio) of the atria of 132 ...

Heart atria granularity effects of changes in water-electrolyte balance.
Experimental Biology and Medicine, 1979 SummaryAtrial granularity was measured using a new morphometric method in rats subjected to procedures known to alter water-electrolyte balance. It was found that water deprivation and sodium deficiency lead to atrial hypergranulation, whereas, the ...
