L. Daliento et al., CLINICAL-SIGNIFICANCE OF HIGH-FREQUENCY, LOW-AMPLITUDE ELECTROCARDIOGRAPHIC SIGNALS AND QT DISPERSION IN PATIENTS OPERATED ON FOR TETRALOGYOF FALLOT, The American journal of cardiology, 76(5), 1995, pp. 408-411
Ventricular arrhythmias, recorded by 24-hour ambulatory monitoring in
patients following total repair of tetralogy of Fallot, are frequent a
nd are considered the most important mechanism of sudden death.(1,2) T
he aim of this study was to assess the usefulness of signal-averaged e
lectrocardiography and QT dispersion as non-invasive investigations fo
r risk stratification of dangerous ventricular arrhythmias in patients
operated on for tetralogy of Fallot.
