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
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.
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.
