Atrial P waves can be diphasic (positive and negative), flattened, or peaked. They may also dip below the isoelectric line (baseline) due to the direction of atrial depolarization. However, they should not be uniformly rounded as this would suggest that the electrical impulse is not originating from the sinoatrial node, but rather from a different location in the atria.
