The QT interval reflects the time it takes the heart\u2019s lower chambers to electrically reset between beats. When this reset is delayed, certain fast and unstable rhythms can become more likely in some situations. The term is commonly used in cardiology to describe inherited forms and acquired (non-inherited) QT prolongation."}
