This is not possible to answer concisely as the EKG can reflect many different abnormalities, some are very subtle, others easy to describe.

The EKG is a way of representing the electrical activity of the heart graphically.

The simplest thing to read on an EKG is the pulse. The EKG should be regular repeating pattern. If not then there is some sort of rhythm disturbance. If the line is flat (as often seen in films and on TV) there is no electrical activity in the heart which means it has stopped.

Other abnormalities that show up change the size and shape of the electrical wave in various ways.

The wave is recorded by attaching leads to each limb and across the chest. Thus the lines on the EKG represent the different electircal 'views' from different parts of the body. This adds to the ability to diagnose the part of the heart that a problem is occuring.

The EKG is a general screening tool that can tell a variety of things, some well and with precision, some not atall. If an abnormality is detected there is usually a need for further tests to confirm or refine the diagnosis.
