P mitrale

P mi·tra·le

(mī-trā'lē), The final e is not silent.
Broad, notched P waves in several or many leads of the electrocardiogram with a prominent late negative component to the P wave in lead V1, presumed to be characteristic of mitral valvular disease. (Although this term is extensively used in electrocardiographic literature, it is actually a misnomer and would be more appropriately called P-sinistrocardiale, as it results from overload of the left atrium regardless of the cause and may occur independently of disease of the mitral valve.)

(1) In addition, P waves in lead II, aVF, and [V.sub.2]-[V.sub.6] are 0.12 seconds in duration (2) and bifid with [greater than or equal to] 0.04 seconds between the two peaks (3)-the two defining features of P mitrale.
Electrocardiography findings were as following: normal sinus rhythm, p mitrale at D1-2 aVR, t (-) at V1-6 derivations.
