The ECG Song (R&B) - How to Read an ECG/EKG

What does the ECG primarily monitor in the heart?

• Blood pressure

• Electrical activity

• Heart rate

• Oxygen levels

Where does the electrical activity recorded by the ECG begin?

• Atria

• SA node

• Ventricles

• AV node

Which wave on the ECG represents the depolarization of the atria?

• U wave

• P wave

• T wave

• QRS complex

What does the QRS complex on an ECG signify?

• Atrial repolarization

• Ventricular repolarization

• Ventricular depolarization

• Atrial depolarization

What is indicated by the T wave on an ECG?

• Atrial depolarization

• Ventricular depolarization

• Ventricular repolarization

• Atrial repolarization
