Through ECG analysis, it is possible to trace the conduction through the heart, the size and orientation of the heart, and even to locate regions of the heart which have suffered injury, ischemia (oxygen deprivation), or necrosis (tissue death).

This tutorial will focus on Lead II ECGs. Lead II implies that the activity is measured from the right arm to the left leg. The ECG will show activity along the septum of the heart.
