Answer: Which statement describes the condition of the heart at the point indicated in the electrocardiogram?

  • The atria are contracting and pushing blood into the bottom ventricles of the heart.

Explanation:

The electrocardiogram is a test that records the electrical activity of the heart. <u>Each beat produces an electrical activity </u>and with an electrocardiograph we can see how that activity is and if there are alterations of the heart rhythm.

The P wave is the first wave of the cardiac cycle.<u> It represents the depolarization of the atria.</u> It is composed of the superposition of the electrical activity of both atria.

Its initial part corresponds to the depolarization of the right atrium and its final part to that of the left atrium.
