Double-chambered left ventricle – a “heart within a heart”
Forensic Science, Medicine and Pathology, 2018A 20-year-old previously well man drowned after performing a back-flip off a bridge into a river. At autopsy no significant injuries or organic illness were identified. An unusual incidental finding was a double chambered left ventricle, or so-called "heart within a heart", with the left ventricle subdivided into two separate chambers by a muscular ...

Actomyosin content of rabbit heart ventricle
American Journal of Physiology-Legacy Content, 1964The requirements for quantitative extraction of rabbit cardiac actomyosin were investigated. Extraction of the tissue was carried out at pH 6.5. Under these conditions, precipitation of actomyosin from the soluble tissue extract showed a plateau between pH 6.9 and 7.1.

The Right Ventricle in Congenital Heart Disease
Cardiology Clinics, 1992An increasing number of children with congenital heart disease are surviving into adulthood, creating new, unusual patients with different physiologic and anatomic problems for the adult cardiologist. This article discusses those lesions affecting primarily the right ventricle.

On the Regional Metabolism of Beef Heart Ventricles
Acta Physiologica Scandinavica, 1973AbstractThe concentrations of some oligoelements (iron, copper, zinc) and electrolytes (calcium, magnesium, potassium) and the activity of the succinate‐cytochrome c reductase system were determined in various regions of the ventricles of beef heart. In the subepicardial layers of the ventricles and in the upper part of the septum a higher content of ...

Diastolic shape of the right ventricle of the heart
The Anatomical Record, 1998Knowledge of right ventricular (RV) shape is important to the understanding of RV mechanical function and for the improvement of clinically important RV volume estimation techniques. Refinements to the simplest conceptions of RV shape are presented statistically here, based on a quantitative analysis of three-dimensional magnetic resonance (MR) images ...

Sodium Exchange in the Frog Heart Ventricle
American Journal of Physiology-Legacy Content, 1957The 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.

Lipid composition of beef heart ventricle
Lipids, 1967AbstractThe lipid class composition of beef heart ventricle was determined by a combination of diethylaminoethyl cellulose column chromatography and quantitative thin‐layer chromatography. Percentages of the total lipid were: triglyceride, 43.6; cholesterol, 7.4; phosphatidyl choline, 22.8; phingomyelin, 4.0; phosphatidyl ethanolamine, 11.2 ...

[Diastolic filling of the heart ventricle].
Kardiologiia, 1983It 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 ...
