What is an ECG?

The electrocardiogram (ECG) is a test that measures the electrical activity of the heart. It records the heart's electrical impulses as waves on a graph.

What does the P wave represent?

The P wave represents the electrical activity of the atria as they contract, pushing blood into the ventricles.

What does the QRS complex represent?

The QRS complex represents the electrical activity of the ventricles as they contract, pushing blood out of the heart.

What does the T wave represent?
