[Non-linear analysis of electrocardiographic signals as a non-invasive predictive tool for major ventricular arrhythmias].
The aim of this study was to assess the effectiveness of different methods of non-linear analysis of the ECG in the risk stratification of patients with ventricular arrhythmias. These non-invasive parameters were correlated with the results of the electrophysiological study (EPS). We evaluated 25 patients with a history of cardiac arrest, syncope, sustained or non-sustained ventricular tachycardia. The study group was compared with a control group of 25 healthy subjects. All patients underwent both EPS and non-linear analysis procedures applied to their ECG recording. A comparison between the results of non-linear analysis of the ECG and EPS was performed. Results are presented and discussed.
