Anatomy and the ECG

• The P wave = atrial activation (SA node to AV node).
• The PR interval = onset of atrial activation to onset of ventricular activation.
• The QRS complex = electrical ventricular activation.
• The ST-T segment = ventricular repolarization.
• The QT interval = the duration of ventricular activation and recovery.

Question

• Calculate the heart rate
