WPW

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.

Etiology

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

Diagnosis

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.

Treatment

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