The p wave morphology can reveal right or left atrial stretch.
The P-wave morphology is best determined in leads II and V1 during sinus rhythm.

Elevation or depression of the PTa segment (the part between the p wave and the beginning of the QRS complex) can result from Atrial infarction or pericarditis.
If the p-wave is enlarged, the atria are enlarged.
If the P wave is inverted, it is most likely an atrial rhythm not originating from the sinus node.
