A recording that detects and amplifies the electrical currents from the beat of the heart

Produced when a signal from the SA node spreads through the atria and depolarizes them

Generated by ventricular repolarization immediately before diastole

Produced when the signal from the AV node spreads through the ventricular myocardium and depolarizes the muscle

Represents the time required for impulses to travel from the SA node to the AV node
