Neet Solved Paper 2013 Question 61
Question: The diagram given here is the standard EGG of a normal person. The P-wave represents the
Options:
A) contraction of both the atria
B) initiation of the ventricular contraction
C) beginning of the systole
D) end of systole
Show Answer
Answer:
Correct Answer: A
Solution:
- In ECG, P-wave represents the depolarization of atria, which leads to the contraction of both atria. T-wave represents the return of ventricles from excited to normal state. The QRS complex represents the depolarisation of the ventricles, which initiates ventricular contraction. The contraction starts shortly after Q and marks the beginning of systole.
