Left, middle: Smaller U waves and those that are separate from the T wave should be excluded from measurements Right: Large U waves that are fused to the T wave should be included in measurements.

This method allows computers in 12 lead equipment to quickly calculate the QTc and print it on the EKG record. It also allows Paramedics to quickly assess the QT interval. QT or QTc intervals that are long suggest abnormal effects on the myocardium. QT prolongation is usually divided into two categories, congenital and acquired.
