References: As the left atrium depolarizes after the right atrium, an enlargement thereof will cause a longer duration of the depolarization time and therefore a widening of the Pwave, greater than 0.12s. Sometimes the right and left component of the Pwave are separated slightly giving the Pwave a form of "letterm" lower case, classically called Pmitrale.
