Question: what is a pqrst wave?
Answer: Basic PQRST: P-wave: The first little “hump” or “bump” you see is known as the P-wave. ... Study 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.
