VENTRICULAR pre-excitation (WPW syndrome) which becomes associated with atrioventricular block (A-V) sometime in its course is rare. The literature of this combination up to 1959 was reviewed by Moret and associates.' Cases have been reported by Feldmann and Koch,2 Segers and associates,3 Coelho,4 Levine and Burge,j Rodstein, Fox and associates,7 Scherf and associates,8 Pick and Katz,9 Zuckerma...

Three patients with recurring attacks of supraventricular tachycardia and no electrocardiographic evidence of the Wolff-Parkinson-White syndrome (WPW syndrome) were studied using intracardiac recordings and atrial stimulation. The findings are interpreted as evidence of a concealed WPW syndrome. In all patients there was antegrade block of the anomalous atrioventricular (A-V) pathway while retr...

Echocardiograms of 52 patients with the Wolff-Parkinson-White (WPW) syndrome were investigated. Abnormal patterns of motion were observed in the left ventricular posterior wall (LVPW) and the interventricular septum (IVS). The abnormal LVPW motion was presumably specific for the syndrome and included early onset of the anterior motion which preceded the first heart sound (S1) and a premature pe...

Successful surgical treatment of all forms of supraventricular tachyarrhythmias is dependent on accurate electrophysiologic guidance. Surgery for WPW syndrome is no longer experimental and should be offered to (1) patients with medically refractory reciprocating tachycardia associated with the syndrome, (2) patients with spontaneous atrial fibrillation who are at risk for sudden death, (3) pati...

In 1930, Dr Louis Wolff, Sir John Parkinson, and Paul Dudley White described a case series of 11 patients with a syndrome that now bears their name.1 The first patient with a short PR interval, ventricular preexcitation, and supraventricular tachycardia was described by Cohn and Fraser in 1913.1 Wood et al postulated the accessory pathway (AP) as its anatomic substrate in 1942, and a large popu...

1 wo previous reports have demonstrated dual AV nodal pathways as the causative mechanism of spontaneous SVT termination in the WPW syndrome. Westveer et al’ reported a patient with WPW and non-sustained antidromic SVT, where SVT termination was related to retrograde dual AV nodal pathways. Retrograde conduction of the SVT occurred over the slow retrograde AV nodal pathway with concealment into...

OBJECTIVES We compared strategies and costs associated with recruiting unmarried middle-aged and older women who partner with women (WPW) and women who partner with men (WPM) into an observational study about experiences with cancer screening. METHODS We used targeted and respondent-driven sampling methods to recruit potential participants. Comparable recruitment strategies were used for WPW ...
