Webatrium and then in the left atrium. Atrial enlargement is best observed in the P waves of leads II and V1. Lead II is oriented parallel to the flow of current through the atrium and is the main P wave vector. V1 is oriented perpendicular to the flow of current through the atrium. This results in a biphasic P wave, in which the first peak WebDec 8, 2024 · Notches and nipples can occur when P waves are embedded in the T waves.
