| atrium pulmonale | left atrium of heart |
|---|---|
| glomus pulmonale | A structure similar to the carotid body, found in relation to the pulmonary artery. Synonym: glomus pulmonale. (05 Mar 2000) |
| cor pulmonale | Enlargement of the right ventricle in the face of pulmonary hypertension that may occur primarily or secondary to emphysema or bronchiectasis. Eventually the enlarged right ventricle weakens resulting in right-sided congestive heart failure. (27 Sep 1997) |
| P-pulmonale | Tall, narrow, peaked P waves in electrocardiographic leads II, III, and aVF, and often a prominent initial positive P wave component in V1, presumed to be characteristic of cor pulmonale. (Although this term is extensively used in the electrocardiographic literature, it is actually a misnomer and would be more appropriately called P-dextrocardiale, since it results from overload of the right atrium regardless of the cause, as in tricuspid stenosis, and may occur independently of cor pulmonale.) In lung disease, P-pulmonale is usually transient, occurring during exacerbations. (05 Mar 2000) |
| ligamentum pulmonale | <anatomy> Two-layered fold formed as the pleura of the mediastinum is reflected onto the lung inferior to the root of the lung. Synonym: ligamentum pulmonale, ligamentum latum pulmonis, Teutleben's ligament. (05 Mar 2000) |
