Sodium Exchange in the Frog Heart Ventricle

American Journal of Physiology-Legacy Content, 1957
The isolated frog heart ventricle was used to study the kinetics of uptake and release of radioactive sodium. Sucrose was used as an extracellular space indicator. A flux of sodium across the ventricle cell membranes of 15 x 10–12 m/cm2 sec. was calculated from the data.

[Fibrillation of the heart ventricles].

Anesteziologiia i reanimatologiia, 1997
During ventricular fibrillation, extra feedback may form in the myocardial structure due to specific features of such fibrillation, specifically, because of highly asynchronous contractions of some parts of the myocardium; these newly forming feedback is conducive to a persistent development of such arrhythmia.

Two-ventricle repair for hypoplastic left heart syndrome

Seminars in Thoracic and Cardiovascular Surgery Pediatric Cardiac Surgery Annual 2001, 2001
Hypoplastic left heart syndrome encompasses a spectrum of structural cardiac malformations characterized by severe underdevelopment of the structures in the left heart-aorta complex. The severe end of the spectrum consists of aortic atresia and mitral atresia, whereas at the mild end patients have aortic valve and mitral valve hypoplasia without ...

ECMO in Single Ventricle Heart Disease

Current Treatment Options in Pediatrics, 2019
Cardiac extracorporeal membrane oxygenation (ECMO) for single ventricle heart disease is a complex intervention applied to a heterogeneous population of children. In this review, we describe the variable single ventricle populations who may be supported with ECMO and highlight recent literature regarding outcomes, trends, and evolving strategies.

[Diastolic filling of the heart ventricle].

Kardiologiia, 1983
It is demonstrated that negative, "subatmospheric" pressure developing in the heart ventricles during the rapid-filling phase is an evidence of active diastole and inflated capacity of heart chambers. Diastolic activity of the heart increases as a result of insufficient blood inflow to the ventricles coupled with inadequate venous return or narrowed ...

[Flow structure in artificial heart ventricle].

Meditsinskaia tekhnika, 1991
The flow structure in the artificial heart ventricle has been investigated by laser knife visualization method using fluorescence. It is shown that the flow structure is essentially three-dimensional. The effect of inlet artificial valve orientation on the flow structure is demonstrated.
