Wide P waves

A wide P wave is more than 3 small squares wide (120 ms) at standard settings. This can be associated with left atrial enlargement, but it is not diagnostic. If the P wave is wide and notched, it may be known as P mitrale because of the association between left atrial enlargement and mitral valve disease.
