Heart Exam

Explain what is happening in the heart for the segment of the ECG electrical signal below.

P Wave

Explain what is happening in the heart for the segment of the ECG electrical signal below

Q-R-S Complex

What is happening in your heart during the P-Q interval that is a relatively flat line area between the Pwave and QRS Complex

What is happening in your heart during the S-T interval that is a relatively flat line area between the QRS Complex and the final T wave

The heartbeat is started by the electrically active cells known as the

• SA Node

• AV Node

• Inter-Atrial node

• Inter- Septal Node

The nerve fibers that run down the muscle wall between the ventricles and carry the electrical signal to the ventricles is called

• Bundle of His

• Inter-Ventricular Bundle

• AV Node

• SA Node

The nerve fibers that run on the outside walls of the ventricles that carry the electric impulses to the myocardium of the ventricles are called

• Purkinji Fibers

• Interventricular Fibers

• AV Node

• Ventricular Bundle
