1.	Which of the following waves represent the excitation of the atria?(a) P-wave(b) QRS complex(c) T-wave(d) ST-segmentI got this question by my school principal while I was bunking the class.The origin of the question is ECG in division Body Fluids and Circulation of Biology – Class 11
Answer» Right answer is (a) P-wave For explanation I would SAY: The P-wave represents the electrical EXCITATION of depolarisation of the atria which LEADS to the CONTRACTION of both the atria. The T-wave represents the repolarisation of the ventricles.
