First-line treatments
Disease management and monitoring
Treatment options should be discussed with a qualified healthcare provider.
Implantable cardioverter-defibrillator (ICD)
Surgical placement of an ICD to monitor heart rhythm and deliver appropriate shocks for life-threatening arrhythmias. Considered first-line for high-risk patients with confirmed diagnosis.
Antiarrhythmic pharmacotherapy
Medications such as quinine or other QT-prolonging agents used cautiously to lengthen the QT interval and prevent arrhythmias. Requires careful cardiac monitoring.
Additional treatment options
Continuous cardiac monitoring
Ambulatory ECG monitoring or implantable loop recorders to detect arrhythmias and assess treatment efficacy. Essential for risk stratification and follow-up.
monitoringArrhythmia trigger avoidance
Lifestyle modifications including avoiding QT-shortening medications, extreme exercise, and known environmental triggers. Stress management and sleep optimization are also important.
lifestyleElectrolyte optimization
Ensuring adequate potassium and magnesium levels through diet and supplementation as needed. These electrolytes are critical for cardiac electrical stability.
