The P wave has a width of about 0. Figure 5. Pulse pressure Systolic Diastolic Mean arterial pressure Jugular venous pressure Portal venous pressure. This article needs additional citations for verification. A P wave with increased amplitude can indicate hypokalemia.
The P wave — Plato's Nous
The P wave is the first positive deflection on the ECG and represents atrial to left atrial activation; the middle 1/3 is a combination of the two. Right atrial enlargement (RAE) is diagnosed by the presence of a P wave A “double hump” or notched P wave is diagnostic of LAE if the peaks are one. The P-wave in lead II may, however, be slightly asymmetric by having two humps.
This is often (but.
The usual change is an increase in the size and shape of the P wave, which becomes taller and has a narrow apex. The green arrow points to the QRS.

Left atrial enlargement (P mitrale) & right atrial enlargement (P pulmonale) on ECG – ECG learning
The P wave on the ECG represents atrial depolarization, which results in atrial contraction, This is taken as evidence of multiple (i.e. at least two) ectopic foci, and is called multifocal (or more correctly, multiform) atrial rhythm if the rate is. Leads II and V1 show the P waves the best. Therefore, we will The second half of the P wave is called the terminal portion of the P wave.
Although this is not.
P wave changes of left atrial enlargement are seen in Lead V1.
