  • P Wave: Atrial depolarization initiated by the SA node.

  • PQ segment: signal travels from SA to AV nodes

  • PR Interval: Time taken for the electrical impulse to travel from the atria through the AV node to the ventricles.

  • QRS Complex: Ventricular depolarization resulting from the spread of the electrical impulse through the ventricles.

  • ST segment: ventricles contract and make blood

  • T Wave: Ventricular repolarization, followed by ventricular relaxation
