Hello everyone, in this question the graph of the ecg has been given to us.
00:06
So, we need to take these steps in order and then we will discuss about this.
00:13
So, here the step 1 says we need to evaluate the p wave.
00:17
So, p wave amplitude should not exceed 3.
00:24
The small squares here it is 3 millimeter or it is 0 .3 millivolt.
00:30
So, in given ecg there is normal p wave.
00:38
Then after that we need to discuss about the arterial rhythm.
00:44
So, here the arterial rhythm is decided by the normal p wave and also the interval between the two p wave.
01:01
So, in this question looking at the graph we can say that there is a normal arterial rhythm.
01:10
Then in the third one we have to calculate the arterial rate.
01:17
So, that will be equals to 1300 divided by p minus p interval.
01:25
So, that here is 13.
01:26
So, this is 300 then 300 divided by 4 that will be 75 arterial rate and then the pr interval between the state of p wave up to the qrs interval.
01:45
So, that will be small square multiplied by 0 .04 seconds...
