P-pulmonale

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.
