We report on a 48-year-old man who presented with recurrent sustained monomorphic ventricular tachycardia, which resulted in syncope on one occasion. Subsequent investigation confirmed the diagnosis of arrhythmogenic right ventricular dysplasia. Familial screening for the disease was conducted using 12-lead electrocardiography, signal-averaged electrocardiography, and magnetic resonance imaging...

This study proposes a method for ventricular late potentials (VLPs) detection using time-frequency representation and wavelet denoising in high-resolution electrocardiography (HRECG). The analysis is performed both with the signal averaged electrocardiography (SAECG) and in real time. A comparison between the temporal and the time-frequency analysis is also reported. In the first analysis the s...

OBJECTIVE Using P-wave signal-averaged electrocardiography, we assessed the patterns of atrial electrical activation in patients with idiopathic atrial fibrillation as compared with patterns in patients with atrial fibrillation associated with structural heart disease. METHODS Eighty patients with recurrent paroxysmal atrial fibrillation were divided into 3 groups as follows: group I - 40 pat...

In this work we introduce a method for the enhancement of Late Potentials in the Signal Averaged electrocardiography. The method involves computation of weights prior averaging. Two fuzzy control techniques are proposed for the derivation of weights. The experimental results indicate the contribution of the method to a more reliable prognosis.
