P, Q, R, S and T each represent a wave of the electrocardiogram (ECG). The waves, and the ECG in general, confer a graphic representation of the hearth's electric activity.
The ECG of a healthy person usually contains three waves, called the P wave, the QRS complex and the T wave. The P wave corresponds to the electric depolarization of the auricles, the QRS complex corresponds to the electric depolarization of the ventricles and the repolarization of the auricles, and the T wave corresponds to the electric repolarization of the ventricles.
A complete period of an ECG (that is, the P, QRS, and T waves) represents the electrical activity of the heart for one pulse.
