The P wave morphology can reveal right or left atrial stretch or atrial arrhythmias and is best determined in leads II and V1 during sinus rhythm.
|Characteristics of a normal p wave:|
If the p-wave is enlarged, the atria are enlarged.
If the P wave is inverted, it is most likely an ectopic atrial rhythm not originating from the sinus node.
