EKG Readings

Front

P Wave

Back

Represents the contraction of the SA node and both atria.

Front

QRS Wave

Back

Correlates with ventricle contraction.

Front

Purkinje Fibers Location

Back

Located at the bottom of the heart, specifically in the ventricular walls.

Front

T Wave

Back

Represents ventricular repolarization.

Front

Ventricle Repolarization

Back

Occurs during the T wave of the EKG.

Front

SA Node Function

Back

Acts as the natural pacemaker of the heart, initiating the heartbeat.

Front

AV Node Function

Back

Delays the electrical impulse to allow the ventricles to fill with blood before contraction.

Front

Bundle of His

Back

Conducts impulses from the AV node to the Purkinje fibers.

Front

Atrial Contraction

Back

Occurs during the P wave of the EKG.

Front

Ventricular Contraction

Back

Occurs during the QRS complex of the EKG.
