A standard electrocardiogram (ECG or EKG) records the heart’s electrical activity. It consists of waves: 1) ordinary, regular waves and 2) abnormal, irregular waves. The standard type of wave is called the QRS complexes. 

These waves show the electrical impulses coming from the heart and tell the doctors what part of the heart is contracting. The abnormal waves are called the T waves. These waves show when the heart muscle is relaxed and not actively acquiring.
