Ekg Waves

What is the name of the circled area of the ECG in the diagram?

• P Wave

• QRS Complex

• T Wave

• Cardiac Cycle

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

During repolarization of ventricles

• the ventricles are relaxing

• the ventricles are contracting

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

P wave is

• Repolarization of atria

• Repolarization of ventricles

• Depolarization of atria

• Depolarization of ventricles

T wave is

• Repolarization of atria

• Repolarization of ventricles

• Repolarization of ventricles and atria

• Depolarization of atria and ventricles

QRS complex is

• Repolarization of atria

• Repolarization of ventricles

• Depolarization of atria

• Depolarization of ventricles

Which event is NOT correct during P wave

• SA node generate impulse and transmit it to walls of atria

• Atrial depolarization

• Atria contract

• Ventricular depolarization

Which of the below are correct during QRS complex event?

• Intensity of impulse is greater than in P wave

• Impulse is transmitted from AV node to the walls of ventricles

• Ventricular repolarization

• Atrial repolarization

Which one is represent P wave

• A

• B

• C

• E
