Analysis of Ventricular Late Potentials in High Resolution Ecg Records by Time-frequency Representations
This study proposes the application of different linear and quadratic Time-Frequency Representations (TFR) for the analysis of Ventricular Late Potentials (VLP) in High-Resolution Electrocardiographic (HRECG) records. The TFR used here were Short-Time Fourier Transform (STFT), Wigner-Ville (WV) and Choi-Williams (CW) distributions. These techniques were used to evaluate the risk of Ventricular ...
متن کاملDetection of Ventricular Late Potentials in High-Resolution ECG Signals by a Method Based on the Continuous Wavelet Transform and Artificial Neural Networks
-Ventricular Late Potentials (VLPs) are low-amplitude, high-frequency signals which appear at the end part of the QRS complex of a High-Resolution ECG (HRECG) record including three orthogonal (XYZ) leads. VLPs are clinically useful in identifying post-MI (Myocardial Infarction) patients prone to Ventricular Tachycardia (VT) and Sudden Cardiac Death (SCD). The Continuous Wavelet Transform (CWT)...
متن کاملVentricular action potentials, ventricular extracellular potentials, and the ECG of guinea pig.
Action potentials were recorded from different regions of the guinea pig ventricle to characterize regional differences in waveform configuration, and to acquire insight into the generation of the T-wave of the electrocardiogram. Isolated tissue preparations were driven at 1 Hz, and microelectrodes were used to map accessible surface regions of the epicardium, endocardium, and septum. There wer...
متن کاملLate ventricular potentials and heavy drinking.
OBJECTIVES To assess the effects of chronic drinking on detection of low amplitude signals, and to determine the relation between late ventricular potentials (LVP) and liver biopsy findings. DESIGN Prospective study. SETTING General hospital. PATIENTS 41 consecutive chronic alcoholics without known pre-existing heart disease. METHODS About four days after each patient's last alcoholic d...
متن کاملPowerline Interference Suppression in High-Resolution ECG
The efficacy of four powerline interference suppression methods was tested for application in highresolution electrocardiogram (ECG). The goal was minimal distortion of the original signal micro-potential waveform, combined with maximum noise reduction. Simulated low amplitude His-bundle potentials were used for the evaluation. Several objective parameters were measured, such as mean square err...
