WebbThe P wave represents depolarization of the atria and is followed by atrial contraction (systole). Atrial systole extends until the QRS complex, at which point, the atria relax. The … WebbThe QT Interval. The QT interval is measured from the beginning of the QRS to the end of the T wave. It represents the time in which the ventricles depolarize and repolarize and is a measure of ventricular action potential (AP) duration. This interval should be determined in the ECG lead where it is longest.

WebbCorrect option is A) An ECG consists of a set of three waves; these are namely the P wave, a QRS complex, and a T wave. Initiation of impulse by SA nodes and its travel through atria is represented by P wave which in turn signals systole of atria and initiation of contraction of atrial myocardium. This makes option A correct answer. WebbThe P-wave is a small, positive and smooth wave. It is small because the atria make a relatively small muscle mass.
