00:00So, some people have difficulty in understanding ECG, so I am going to tell you the solution to this in this video.
00:06So, first of all, what does P-Wave represent?
00:09P stands for right atrium, left atrium, right ventricle, left ventricle.
00:14So, the initiation of P-Wave occurs when there is a contact between the right atrium and the left atrium.
00:23So, the blood that is above the contraction will flow to the lower atrium.
00:26So, P-Wave ends here.
00:28After that, P-R-Wave remains silent.
00:31This is the time when both the ventricles fill up.
00:34Now, Q-R-S.
00:36Q-R-S complex has filled up in the ventricle.
00:39So, the heart has to pump.
00:41Now, this will pump to supply more space.
00:44Q-R-S means both ventricle contraction.
00:47It is called systole.
00:49In Q-R-S complex, the ventricle is systole.
00:52After that, look at P-Wave.
00:54P-Wave means ventricle relaxation.
