"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. " - In an ekg what does the p wave represent
