WOLFF-PARKINSON- WHITE SYNDROME

Wolff–Parkinson–White syndrome (WPWS) is a disorder due to a specific type of problem with the electrical system of the heart which has resulted in symptoms

Diagnosis

Present in 1% of population.

Ventricular pre-excitation via an accessory pathway that bypasses the AV node.

ECG shows short P-R interval, delta-wave (slurred upward R-wave especially in chest leads).

Paroxysmal tachycardias can occur with variable width QRS and bizarre ECGs and hypotension.

Management

1. If stable treat tacyarrhythmias with Flecanide 150 mg IV (2 mg/kg) over 30 mins,

2. Beware using Adenosine or Verapamil as they might increase ventricular response,

3. DC conversion if unstable,

4. Ablation therapy might be needed at a later date.
