Hello,
I don't know if I'm posting this in the right section because I need help with reading EKG graphs (and I've never had any experience with them), but I'm doing this for my physics lab class.
I attached the graph I need help with.
So basically, one period on the graph means one cardiac cycle, right?
From the graph attached I have to figure out the "feature" that is in the 1st cycle but not in the 2nd or 3rd.
I can't see the difference between the cycles. They all have an isoelectric line.
I think I can see that the 2nd and 3rd cycles fail to show the repolarization of the atrium, which is where the the voltage falls slightly and makes a Q wave then after that is an R wave and then the S wave, the lowest voltage.
Or maybe it doesn't show just the last part (going from R to S), which is the contraction of the ventricles.
