The clinical characteristics of ventricular
tachycardias (VT) due to arrhythmogenic right ventricular dysplasia (ARVD) are now well
known1,2, even if many aspects of this disease remain
unclear, like its aetiology as well as the relationship between the clinical
characteristics of the disease and the occurence of VT. In ARVD, several typical ECG
changes have been described3,4, and one of the most
important clinical characteristics is the large prevalence of late potentials5,6. However, the changes in these ECG characteristics of
the disease with time are not well documented.
We prospectively recorded 12-lead ECG and signal-averaged (SA)-ECG in a series of
patients with ARVD, and we looked at their changes during the follow-up.
