EKG Paper

The EKG paper is where the heart rhythm is printed where it can be analyzed carefully and treated accordingly. EKG interpretation takes a bit of skill because there are certain EKG rhythm print outs that are difficult to identify.

Let's look at the piece of graph paper to show you how the heart rate is measured:

Graph Paper

As you can see on the graph paper above, each small square is 1 mm in length and represents 0.04 seconds and each larger square is 5 mm in length and represents 0.2 seconds.

Each large square has 5 small squares each at 0.04X5 = 0.2 seconds.

Here is a sample of a cardiac rhythm print out on an EKG graph paper.
