Role of His-Purkinje System in the Initiation of Orthodromic Tachycardia in Wolff-Parkinson-White Syave been extensively studied [1–10]. The most common arrhythmia in this patient population is the reciprocating tachycardia utilizing the normal pathway in one direction and the accessory pathway in the other. Less commonly, the accessory pathway may constitute both the anterograde and retrograde li

Response of Accessory AV Pathways to Exercise and Catecholamines]. Furthermore, recent reports have provided evidence that accessory pathway properties may be influenced by exercise and catecholamines [4–8]. Most of the data available concern atrioventricular (AV) pathways, and we shall focus our discussion on this type of accessory connection which is associate

Preexcitation Syndromes Associated with Congenital Heart Diseasetion. The simultaneous occurrence of preexcitation syndromes with tachyarrhythmias and certain types of congenital heart disease — for example, Ebstein’s malformation — is not unexpected, considering the developmental abnormalities and anatomic substrates involved. Each separate problem may affect t
