[Treatment of Wolff-Parkinson-White syndrome associated with asthma]

We performed division of accessory pathways in five asthma patients associated with Wolff-Parkinson-White (WPW) syndrome, for whom the administration of a beta-blocker for the tachycardia is contraindicated, and the administration of bronchodilators for the asthma attack may cause premature ventricular contractions. As a result, the tachycardic attacks disappeared postoperatively, both at rest and following administration of bronchodilators. Radical treatment of WPW syndrome by division the accessory pathway is considered to be necessary for the safe treatment of asthma.
