Many common meds can prolong the time interval between the Q wave and the T wave on an ECG heart monitor. A long "QT interval" can lead to serious irregular heart rhythms or even sudden death.
The good news is that it's rare. But the balance can tip depending on the patient's risk, meds, and doses used.
