Wolff-Parkinson-White syndrome

a congenital abnormality of heart conduction caused by the presence of an extra (accessory) conduction pathway between the atria and ventricles (see atrioventricular bundle). It results in premature excitation of one ventricle and is characterized by an abnormal wave (delta wave) at the start of the QRS complex on the electrocardiogram. The accessory pathway predisposes the patient to episodes of fast heart rate (supraventricular tachycardia) due to the rapid self-sustaining circulation of an electrical impulse from the atria to the ventricles and back again (a re-entry circuit). Emergency treatment is in the form of drugs that temporarily block the re-entry circuit. Permanent destruction of the accessory pathway by radiofrequency ablation is usually curative [Wolff; Sir J. Parkinson (1885–1976), British physician; P. D. White (1886–1973), US cardiologist]
