Correct Answer is A
Explanation
a. QRS wave: The ECG (electrocardiogram) measures the electrical activity of the heart. The QRS complex represents ventricular depolarization, the spread of electrical excitation through the ventricles causing them to contract.
b. P wave: The P wave represents atrial depolarization, the electrical impulse moving through the atria.
c. T wave: The T wave represents ventricular repolarization, the ventricles relaxing after contraction.
d. U wave: The U wave is a small wave of uncertain origin, not related to ventricular depolarization.
