WebThe P wave represents the depolarization of the left and right atrium and also corresponds to atrial contraction. Strictly speaking, the atria contract a split second after the P wave begins. Because it is so small, atrial repolarization is usually not visible on ECG. What ECG has no P wave? Webof the P-wave, if present, to the QRS-complex. If there is a P wave before each QRS and the P is in the same direction as the QRS, the rhythm can be said to be sinus. For instance note in the EKG segment below that there is a P-wave before each QRS (highlighted in blue) and that it is pointing up as is the QRS segment.
