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

Ventricular Preexcitation: Historical Overview The years 1903 to 1912 were particularly banner ones with many arrhythmias being defined, bundle branch function explored, and heart block explained. Indeed the first electrocardiographic abnormality attracting the attention of Einthoven [1] was a bundle branch block (in 1894), recorded by capillar

Anatomic Basis for Preexcitation Syndromesnode is a region in which impulse conduction is normally delayed. Although the mechanism for the this delay is not agreed upon, it is an important feature of the AV node which helps to maintain an orderly sequence of atrial and ventricular contraction. However, there are several potential routes, by

Electrocardiographic Aspects of the Preexcitation Syndromesch results in early excitation of the ventricles and can result in deformation of the QRS complex. This unusual excitatory sequence coined “anomalous atrioventricular excitation” [1] or “preexcitation” [2] interested early electrocardiographers and was reported in isolated cases or small series by C

Here, a minute intravenous dose of a radiopharmaceutical permits image characterization and often, quantification of some quality of the cardiac whole. The radiation dose is smal

The Spectrum of Tachyarrhythmias in Preexcitation Syndromes in severity from mild to life-threatening. Therefore, many patients with preexcitation syndromes and tachyarrhythmias will require treatment. The most appropriate form of therapy for these patients will depend upon the particular mechanism of the tachyarrhythmia. Although invasive electrophysiologi
