I think you mean QT prolongation, which means that the duration of ventricular systole is lengthened. In practical terms, it means that the period of ventricular relaxation is prolonged, because most of the QT-interval is composed of the ST-segment, which signifies the relaxation period.
QT prolongation may be congenital, or more-commonly secondarily caused by side-effects of drugs.

There is no such thing. Maybe you are think of Prolonged QT interval
The waves are named P, Q, R, S, and T there are also intervals PR and QT.
If the QT interval is longer than normal it is said to be prolonged. This can happen for many reasons, the most is medications
