WebIt is important to remember that the P wave represents the sequential activation of the right and left atria, and it is common to see notched or biphasic P waves of right and left atrial activation. P duration < 0.12 sec P amplitude < 2.5 mm Frontal plane P wave axis: 0° to +75° May see notched P waves in frontal plane QRS Complex WebStudy tip: The P-wave represents ATRIAL DEPOLARIZATION (depolarization is a big, fancy word for CONTRACTION). QRS Complex: The next area you see is a big spike. This spike is called the QRS complex. The bundle of His, bundle branches, and Purkinje fibers are responsible for this.
