Which of the following represents the depolarisation of the ventricles

1.	Which of the following represents the depolarisation of the ventricles?(a) P-wave(b) T-wave(c) QRS complex(d) PQ intervalThis question was posed to me by my school principal while I was bunking the class.I'm obligated to ask this question of ECG topic in section Body Fluids and Circulation of Biology – Class 11
Answer» Correct CHOICE is (c) QRS COMPLEX Explanation: The QRS complex represents the depolarisation of the ventricles, which initiate the ventricular contraction. The contraction STARTS shortly after Q and marks the beginning of the systole.
