Wolff-Parkinson-White syndrome

[Louis Wolff, U.S. cardiologist, 1898–1972; Sir John Parkinson, Brit. physician, 1885–1976; Paul Dudley White, U.S. cardiologist, 1886–1973]


A disease manifested by occasional episodes of potentially life-threatening tachycardia, in which there is an abnormal electrical pathway in the heart connecting the atria to the ventricles.


In some families, the disease is transmitted as an autosomal dominant trait.


In electrocardiography, the P-R interval is less than 0.12 sec and the QRS complex is widened as a result of an initial electrical deflection, called the delta wave.


Ablation of the abnormal accessory pathway cures about 92% of patients.
