Erratum to: The right ventricle: interaction with the pulmonary circulation
The primary role of the right ventricle (RV) is to deliver all the blood it receives per beat into the pulmonary circulation without causing right atrial pressure to rise. To the extent that it also does not impede left ventricular (LV) filling, cardiac output responsiveness to increased metabolic demand is optimized. Since cardiac output is a function of metabolic demand of the body, during st...
متن کاملThe right ventricle and pulmonary circulation: basic concepts.
The primary purpose of the right ventricle and pulmonary circulation is gas exchange. Because gas exchange occurs in thin, highly permeable alveolar membranes, pulmonary pressure must remain low to avoid pulmonary edema; because the right ventricle and the lungs are in series with the left ventricle and the systemic circulation, the entire cardiac output must pass through the lungs. This low pr...
متن کاملCirculation time determinations from the right ventricle.
The determination of the circulation time from the ventricle to the face using fluorescein and ultraviolet light eliminates all of the variable factors from the venous side of the circulation and gives evidence specifically of the presence or absence of an intraventricular right to left shunt. The most important clinical application is the differentiation of tetralogy of Fallot from pulmonary v...
متن کاملWhere is the right ventricle?
To cite: Oylumlu M, Dogan A, Ercan S, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2013-202760 DESCRIPTION A 20-year-old man with no history of known cardiac disease was admitted with dyspnoea on exertion during a few weeks. His effort capacity was class I. At physical examination, his blood pressure was 120/ 70 mmHg and pulse 80 bpm. His physical exami...
متن کاملThe right ventricle in pulmonary arterial hypertension.
Pulmonary arterial hypertension (PAH) is a right heart failure syndrome. In early-stage PAH, the right ventricle tends to remain adapted to afterload with increased contractility and little or no increase in right heart chamber dimensions. However, less than optimal right ventricular (RV)-arterial coupling may already cause a decreased aerobic exercise capacity by limiting maximum cardiac outpu...
