P pulmonale

P pul·mo·na·le

(pul'mō-nā'lē), The final e is not silent.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 should be more appropriately called P-dextrocardiale, because 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, usually asthmatic.

P pulmonale

A sharply peaked P wave on EKG, which is a nonspecific finding that may be found in chronic obstructive pulmonary disease (COPD), and is most prominent during exacerbation of clinical disease. Other EKG findings in COPD include a right axis shift, early R waves in the precordial leads V1 and V2, and net negativity in V5 and V6.

'P' pulmonale

Cardiology A sharply peaked P wave on EKG, which is a relatively nonspecific finding of COPD, most prominent during exacerbation of clinical disease. See Chronic obstructive pulmonary disease.

P pul·mo·na·le

(pul-mō-nā'lē) Tall, narrow, peaked P waves in electrocardiographic leads II, III, and aVF, and often a prominent initial positive P wave component in V₁; it is characteristic of right atrial enlargement such as occurs in pulmonary disease and tricuspid stenosis.
