Non-Linear Analysis of ECG Signals as a Method for the Prognosis of Life Threatening Tachyarrhythmias

In order to prevent sudden cardiac death (SCD) it is crucial to precisely identity increased risk for serious ventricular tachyarrhythmias. The aim of this study was to develop a new prognostic method, based on the non linear analysis of ECG signals, and evaluate its role as a marker of sudden cardiac death. In this paper we present the results obtained in fifty patients, by this novel method that show a high predictive value, together with an extremely low cost, in comparison with the invasive technique based on controlled endocavitary ventricular stimulation.
