The dimensionally correct form of Bazett's formula is: = where QTc B is the QT interval corrected for heart rate, and RR is the interval from the onset of one QRS complex to the onset of the next QRS complex. This dimensionally correct formula returns the QTc in the same units as QT, generally milliseconds.

Long QT syndrome (LQTS) is a condition affecting repolarization (relaxing) of the heart after a heartbeat, giving rise to an abnormally lengthy QT interval. [7] It results in an increased risk of an irregular heartbeat which can result in fainting, drowning, seizures, or sudden death. [1]

The value for a normal QT interval is similar in males and females from birth up to adolescence. During infancy, a normal QTc is defined as 400 ± 20 milliseconds. Before puberty, the 99th percentile of QTc values is 460 milliseconds. After puberty, this value increases to 470 milliseconds in males and 480 milliseconds in females. [citation needed]
Those affected by short QT syndrome (SQT) have an increased risk of developing abnormal heart rhythms. [3] These abnormal heart rhythms often occur at a young age. They may take relatively benign forms such as atrial fibrillation, leading to symptoms of palpitations, breathlessness, or fatigue. [3]
