Expected Duration

Inherited long QT syndrome does not go away. If you have a long QT interval caused by a medication you are taking or by a mineral imbalance, it will most likely go away once you stop taking the medication or treat the imbalance. Note that if one type of medication causes you to have a prolonged QT, other medications that affect the QT interval will likely affect you in the same way. Ask your doctor about this any time you are starting a new medication.
