Electrocardiograph <unk>  are defined as<unk>  abnormalities, which are a measurement of cardiac potentials on the body surface and are not related to electrical activity of the heart. As a result of<unk> , normal components of the<unk>  can be distorted. It is very important to recognize these<unk> , otherwise they can lead to unnecessary testing and therapeutic interventions. In this chapter, we will present the common causes and ways to characterize<unk> .
EKG artifacts
Wide complex tachycardia
Supraventricular arrhythmias
Sinus arrhythmia
Torsades de pointes
Atopy
Narrow complex tachycardia
Third degree AV block
