      The normal P wave is less than 0.12 seconds in duration, and the largest deflection, whether positive or negative, should not exceed 2.5 mm. An abnormal P wave may indicate atrial enlargement. Atrial depolarization follows the discharge of the sinus node. Normally depolarization occurs first in the right atrium and then in the left atrium.

      P waves represent atrial depolarisation and are best viewed in Leads II and V1. Left atrial enlargement is suggested by the presence of a notched, widened P wave of more than 2.5 mm or a biphasic P wave in V1. In contrast, a tall P wave of more than 3 mm in infants below 6 months and 2.5 mm in older children suggests right atrial enlargement ...
