Circulation: Ecg
Easybiology
Which ECG wave corresponds to ventricular depolarization?
Select the correct option:
Solution
Incorrect! Answer:
QRS complex
- Electrocardiogram (ECG): A recording of the heart's electrical activity.
- Wave Components:
- P wave: Represents atrial depolarization (contraction of atria).
- QRS complex: Represents ventricular depolarization (contraction of ventricles). It is much larger than the P wave because the ventricles have more muscle mass.
- T wave: Represents ventricular repolarization (recovery phase).
- Note: Atrial repolarization occurs during the QRS complex but is masked by the larger ventricular signal.
