BACKGROUND Atrial flutter with 1:1 atrioventricular conduction via an accessory pathway is an uncommon presentation of Wolff-Parkinson-White syndrome not previously reported in the emergency medicine literature. Wolff-Parkinson-White syndrome, a form of ventricular preexcitation sometimes initially seen and diagnosed in the emergency department (ED), can present with varied tachydysrhythmias fo...

Atrial fibrillation was induced during an electrophysiology study in 10 patients with the Wolff-Parkinson-White (WPW) syndrome, after determination of baseline properties of the accessory atrioventricular (AV) connection; intravenous propranolol (0.2 mg/kg) was then administered. Atrial fibrillation terminated during the drug infusion in three patients, allowing determination of propranolol's e...

Measuring the minute volume of blood flow through an extremity at rest, or in response to a physiological stimulus, offers a useful means of evaluating the status of its vascular bed. Hewlett and Van Zwaluwenburg (1) used for this purpose a plethysmograph based upon the principle demonstrated by Brodie (2) wherein sudden occlusion of the veins draining the limb produces an increase in limb size...

OBJECTIVE To evaluate characteristics of patients and accessory pathways as well as additional technical factors involved in the reappearance of accessory pathway conduction after successful ablation. DESIGN Analysis of recurrences after radiofrequency ablation. SETTING 163 consecutive patients with 167 accessory pathways. SUBJECTS 97 men and 66 women with a mean (SD) age of 36 (14) range...
