Which one of the following statements regarding Electrocardiogram is correct ?

Options

  1. AElectrocardiogram is graphical representation of electrical activity of cornea
  2. BElectrocardiogram is graphical representation of activity of kidney
  3. CElectrocardiogram is graphical representation of activity of brain
  4. DElectrocardiogram is graphical representation of electrical activity of heart

Correct answer

D. Electrocardiogram is graphical representation of electrical activity of heart

Step-by-step solution

An electrocardiogram (ECG or EKG) is a test that checks how your heart is functioning by measuring the electrical activity of the heart. With each heart beat, an electrical impulse (or wave) travels through your heart. This wave causes the muscle to squeeze and pump blood from the heart.
