However, a pronounced notch with a peak-to-peak interval of >0.04 s suggests left atrial enlargement. Right Atrial Enlargement (RAE) P wave amplitude > 2.5 mm in II and/or > 1.5 mm in V1 (these criteria are not very specific or sensitive) Better criteria can be derived from the QRS complex; these QRS changes are due to both the high incidence of RVH when RAE is present, and the RV displacement by an enlarged right atrium. You said "possible LAE", right. P-waves with constant morphology preceding every QRS complex. Echocardiograms are considered the gold-standard for diagnosis, but given their wider access and lower economic cost .
