Question

The spread of the impulse through the ventricles (ventricular depolarization) is depicted on the ECG as the:

Answer 1

Given what we know, we can confirm that when reading an ECG, the ventricular depolarization will be depicted as the QRS complex.

What does each wave represent?

In an ECG, each wave or group of waves represents a different aspect of the heartbeat. The values are as follows:

• The P wave represents atrial depolarization.
• The QRS complex then shows ventricular depolarization.
• The T wave represents ventricular repolarization.

Therefore, we can confirm that when reading an ECG, the ventricular depolarization will be represented by the QRS complex.
