The management of patients with suspected Wolff-Parkinson-White Syndrome--a four year review.

Abstract

Abstract: Thirty‐six patients with the electrocardiographic pattern of Wolff‐Parkinson‐White (WPW) Syndrome had electrophysiological (EP) studies over a four year period. Thirty‐two patients were symptomatic and supraventricular tachycardia (SVT) or atrial fibrillation (A Fib) had been demonstrated in 19 of these patients. Four patients were asymptomatic. The diagnosis of WPW was confirmed in 33 of the 36 patients at EP studies and in 24 of 33 the location of the accessory atrioventricular connection (AAVC) from the surface ECG was confirmed at EP studies. The effective refractory period of the AAVC in 30 patients ranged from 200–550 ms (m 284 ± 58 ms). A Fib could be induced in 20 of the 32..
