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.
The normal P wave
Characteristics of a normal p wave:
- The maximal height of the P wave is 2.5 mm in leads II and / or III
- The p wave is positive in II and AVF, and bifasic in V1
- The p wave duration is usually shorter than 0.12 seconds
If the p-wave is enlarged, the atria are enlarged.
