A Method for Ventricular Late Potentials Detection Using Time-Frequency Representation and Wavelet Denoising
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...
متن کاملDetection of Wavelet Transform-Processed Ventricular Late Potentials and Approximate Entropy
Ventricular Late Potentials (VLPs) are low-level highfrequency signals that are usually found within the terminal part of the QRS complex from patients after Myocardial Infarction. Patients with VLPs are at risk of developing Ventricular Tachycardia, which is the major cause of death of patients suffering from heart disease. In this study, the Continuous Wavelet Transform was used to detect VLP...

متن کاملDenoising and Time-window selection using Wavelet-based Semblance for improving ERP detection
Wavelet denoising has been successfully applied to Event-Related Potential (ERP) detection, but it usually works using channels information independently. This paper presents an adaptive approach to denoise signals taking into account the channels correlation in the wavelet domain. Moreover, we combine phase and amplitude information to automatically select a time window which increases ERP det...
متن کاملUsing Supervised Fuzzy Clustering and CWT for Ventricular Late Potentials Detection in HRECG Signal
Ventricular Late Potentials (VLPs) are lowamplitude, high-frequency components that appear at the end of the QRS complex of a High-Resolution ECG (HRECG) record. VLPs are clinically useful for identifying post-MI (Myocardial Infarction) patients prone to Ventricular Tachycardia (VT) and Sudden Cardiac Death (SCD). In this paper, the Continuous Wavelet Transform (CWT) and a supervised fuzzy clus...
