PQRST an electrical event
An EKG is an electrical waveform recording that records each cardiac cycle of contraction (systole) and relaxation (diastole). These electrical events are what produce the basic waves and lines of the standard EKG. Please see below. The P wave is produced by atrial contraction or depolarization represented by the upward curve of the image below. The QRS is produced by ventricular contraction or depolarization which is represented by the next wave which may have several variations. This electrical waveform begins with a downward deflection or the Q wave, the next and first upward deflection or the R wave, and the next downward deflection after the upward deflection is called the S wave. The T wave is the electrical representation of the ventricles end of depolarization and the start of ventricular repolarization or relaxation.

As a psychiatric nurse I have not had very much experience with reading or offering an opinion about EKGs but the information you have provided is very clear and your add ons really were an enhancement to a student learning and retaining the information.
