The elements of a single cardiac cycle include the P wave (representing atrial depolarization), PR segment (representing atrial contraction), PR interval (time for atrial depolarization and contraction), QRS complex (representing ventricular depolarization), and T wave (representing ventricular repolarization). The ST segment is not considered a distinct element of the cardiac cycle, but rather a period of time between ventricular depolarization and repolarization.
