Wolff-Parkinson-White Syndrome--current views.

E K Chung

    The American Journal of Medicine

    Summary

    Wolff-Parkinson-White (WPW) syndrome involves rapid heart rhythms, often mimicking heart attacks. Early recognition of delta waves and appropriate drug therapy or interventions are key to managing WPW syndrome effectively.

    Area of Science:

    • Cardiology
    • Electrophysiology

    Background:

    • Wolff-Parkinson-White (WPW) syndrome is characterized by recurrent, rapid tachyarrhythmias.
    • Electrocardiographic findings can mimic myocardial infarction, necessitating careful diagnosis.
    • The underlying mechanism involves reentry via anomalous atrioventricular pathways.

    Purpose of the Study:

    • To highlight the diagnostic criteria for WPW syndrome.
    • To review the pharmacological and interventional treatment strategies for WPW-associated tachyarrhythmias.

    Main Methods:

    • Diagnostic criteria emphasize delta wave recognition.
    • Pharmacological management includes propranolol, digitalis, lidocaine, procainamide, and quinidine.
    • Interventional options include DC shock, pacemakers, and surgery for refractory cases.

    Main Results:

    • Delta waves are crucial for WPW diagnosis, though short PR or broad QRS may be absent.
    • Propranolol and digitalis are effective for regular supraventricular tachycardias.
    • Lidocaine, procainamide, or quinidine are preferred for atrial fibrillation/flutter with anomalous conduction.

    Conclusions:

    • Effective management of WPW syndrome relies on accurate diagnosis and tailored treatment.
    • Pharmacotherapy is the mainstay for many patients, with long-term drug therapy often required.
    • Urgent and refractory cases may necessitate electrical cardioversion, pacing, or surgical intervention.
