Non-invasive diagnosis of concealed Wolff-Parkinson-White syndrome by detection of concealed anterograde pre-excitation.
Electrophysiological findings suggest that concealed anterograde conduction through accessory pathways may exist even during sinus rhythm in patients with so-called concealed Wolff-Parkinson-White (WPW) syndrome. To evaluate the pre-excitation characteristics in various types of WPW syndrome, high-resolution electrocardiograms were analyzed in 81 consecutive WPW syndrome patients and 50 age-mat...
متن کاملin Concealed Wolff - Parkinson - White Syndrome *
Two patients with a history of paroxysmal supraventricular tachycardia but no evidence of the Wolff-Parkinson-White syndrome in the conventional electrocardiograms were studied utilizing atrial and ventricular extrastimuli. The evidence obtained in these patients was consistent with a concealed Wolff-Parkinson-White syndrome. In one patient,, ventricular extrastimuli revealed three different re...
متن کاملVentricular Activation in the Pre-Excitation Syndrome (Wolff-Parkinson-White)
Seventy cases pre-excitation were by vector transilating, properties of the delta event are described that are useful in the recognition of this syndrome electrocardiographically. In about half the cases a ventricular conduction defect without QR S-interval prolongation was demonstrated to have accompanied the pre-excitation. The type of ventricular conduction defect produced depended upon the ...

متن کاملAnalysis of Re - entry Mechanisms in Three Patients with Concealed Wolff - Parkinson - White Syndrome
Three patients with recurring attacks of supraventricular tachycardia and no electrocardiographic evidence of the Wolff-Parkinson-White syndrome (WPW syndrome) were studied using intracardiae 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...
