Recommendation 1 (Disclosure): When clinicians prescribe methadone, they should inform patients about arrhythmia risk.
Recommendation 2 (Clinical History): Clinicians should ask patients about any history of structural heart disease, arrhythmia, or syncope.
Recommendation 3 (Screening): All patients should have a pretreatment electrocardiogram (ECG) to measure QTc interval and a follow-up ECG within 30 days and each year.
