1/ Let’s talk about P waves #CardioTwitter.
The P wave is the first positive deflection on the EKG and represents atrial depolarization. The first half represents right atrial depolarization and the second half represents left atrial depolarization.

3/ Peaked P wave
The morphology is peaked with amplitude ≥2.5 mm, usually in II, III and aVF.
The peaked P wave is a typical characteristic of right atrial abnormality/enlargement.
Causes: PE, COPD, congenital heart disease, pulmonary hypertension, normal variant, others.
