Quizplus · Accepted Answer

On the EKG,the waves (P,Q,R,S,T)are electrical voltages produced by the heart and recorded by leads placed on the body.When the atria depolarize,the P wave is produced.During this period,the pressure in the atria exceeds that in the ventricles,thus forcing blood from the atria into the ventricles.After the appearance of the P wave,the QRS complex on the EKG occurs as the ventricles are electrically depolarized.As the ventricles begin to repolarize,the T wave appears on the EKG.The downslope of the T wave indicates the end of ventricular repolarization and the beginning of a relaxation period.
