• Bundle of His

• Purkinje fibers

What is #3?

• SA node

• AV node

• Bundle of His

• Purkinje fibers

What is #5?

• left bundle branch

• junctional fibers

• right bundle branch

• Purkinje fibers

What is #6?

• left bundle branch

• junctional fibers

• right bundle branch

• Purkinje fibers

Which part will send signal to right and left bundle branches?

• #3

• #4

• #5

• #6

What is the correct order of the cardiac conduction system?

• SA node -> bundle branches -> AV node -> purkinje fibers

• SA node -> AV node -> bundle of his -> bundle branches -> purkinje fibers

• AV node -> SA node -> bundle of his -> bundle branches -> purkinje fibers

• Junctional fibers ->AV node ->SA node

ECG stand for

• Electrocardiograph

• Electrocardiogram

• Electrocardiopraphy

• Electronicardiogram

ECG is a reading that shows

• the activity of heart

• the electrical activity of cardiac muscle

• the systole and diastole of cardiac muscle

• the initiation of heartbeat

The correct sequence of the three events in ECG

• P wave , T wave , QRS complex

• QRS complex , P wave , T wave

• T wave , QRS complex , P wave

• P wave, QRS complex, T wave
