The diagram given here is the standard ECG of a normal person. The P - wave represents the:
End of systole
Contraction of both the atria
Initiation of the ventricular contraction
Beginning of the systole
Steps to obtain a standard ECG -
Each peak in the ECG is identified with a letter from P to T that corresponds to a specific electrical activity of the heart.
- wherein
P - wave represents contraction of both atria, which is associated with both left and right atrial depolarization
Option 1)
End of systole
Option is Incorrect
Option 2)
Contraction of both the atria
Option is Correct
Option 3)
Initiation of the ventricular contraction
Option is Incorrect
Option 4)
Beginning of the systole
Option is Incorrect
