What Are Some Tips for Reading and Understanding EKG Strips?


Quick Answer

Different parts of the EKG strip graph represent an electrical signal's journey through the heart during an electrocardiogram, explains the National Heart, Lung, and Blood Institute. The electrical pattern represented on the graph is divided into waves that represent the location of the signal within the heart.

The EKG strip patterns begin with the P wave, which represents the electrical signal moving through the atria, according to the National Heart, Lung, and Blood Institute. The QRS wave pattern illustrates the quick movement of the signal through the ventricles, while the heart is contracting to pump blood to the rest of the body. The T wave is recorded during the recovery of the ventricles to their normal electric state. Once this process is complete, another cycle begins when the heart refills with blood, creating another set of waves on the EKG strip.
