Because trazodone can affect the QT interval, anyone with a personal history of arrhythmia, unexplained fainting, or a family history of long QT syndrome or sudden cardiac events should discuss this specifically before starting trazodone. Prescribers may order a baseline ECG or choose a lower starting dose in these situations.
