This document provides information about reading and interpreting electrocardiograms (EKGs), including the following key points: 1. When reading an EKG, one should examine the rhythm, rate, axis, signs of chamber enlargement, evidence of ischemia or injury, intervals between waves, and provide an overall conclusion. 2. A normal EKG has a regular rhythm with each P wave followed by a QRS complex. It also has normal amplitudes and durations for the various waves as well as normal axes determined by the leads. 3. Abnormalities that can be identified on EKG include signs of right or left atrial and ventricular enlargement as well as conditions like ischemia, injury, and arrhythm
