Heart failure is a common syndrome that is associated with changes in autonomic activity. The analysis of heart rate variability provides information about autonomic status. There are few data on the circadian behavior of HRV in patients with heart f

The frequency domain analysis of the P-wave signal-averaged ECG (P-SAECG) is able to identify patients at risk for lone atrial fibrillation (AF) after cardioversion to sinus rhythm. The terminal portion of the P-wave of right precordial leads on 12-l

Ventricular late potentials (VLP) are fragmented electrical activities, originating from regions with delayed conduction in the damaged myocardium, and markers of ventricular arrhythmia due to reentry. Individuals infected by the human immunodeficien

The Ventricular Late Potentials (VLP) are low amplitude signals originating from electrically unstable regions of damaged myocardium. Due to low amplitude, VLP are detected on the body surface by statistical techniques and band-pass filtering to redu

The analysis of the ventricular late potentials (VLP) has been considered a valuable diagnostic tool for stratification of patients at risk of life threatening arrhythmia. This study evaluates the prevalence of VLP in a late phase post-myocardial inf

Introduction: In chronic chagasic patients sudden death has been reported when QT interval dispersion is increased and antibodies with muscarinic-like activity have been demonstrated to trigger arrhythmias. The aims were to investigate, in vivo and i
