On the basis of the morphology of the T-wave alternans: A Poincare mapping method research
Presently T-wave alternans (TWA) has become a clinical index of non-invasive diagnosis for heart sudden death prediction, and detecting T-wave alternate accurately is particularly important. This paper introduces an algorithm for detecting TWA using Poincare mapping method which is a technique for nonlinear dynamic systems to display periodic behavior. Sample series of beat to beat cycles were ...
متن کامل{T} Wave Alternans Features for Automated Detection
T wave features suitable for automatic T wave alternans detection in low signal-to-noise ratio electrocardiograms are explored using a correlation-to-template-based algorithm for detecting T waves of variable duration. Amplitude and area features of T waves are found to be notably less sensitive to template selection than are duration features. T wave alternans features and measures which can b...
متن کاملA multichannel decision-level fusion method for T wave alternans detection.
Sudden cardiac death (SCD) is one of the most prominent causes of death among patients with cardiac diseases. Since ventricular arrhythmia is the main cause of SCD and it can be predicted by T wave alternans (TWA), the detection of TWA in the body-surface electrocardiograph (ECG) plays an important role in the prevention of SCD. But due to the multi-source nature of TWA, the nonlinear propagati...
متن کاملAssessment of T-wave morphology for detection of T-wave alternans in ECG signals
In this paper, a robust T-wave Alternans (TWA) detection system based on waveform features is proposed. First of all, some repolarization indices are extracted from T-waves and their relationship with TWA is investigated using statistical t-test to select suitable features for detecting TWA. Then, the series of absolute differences between consecutive even and odd beats are calculated for prope...
متن کاملMalignant T-wave alternans.
A36-year-old woman was referred after her son had syncopal episodes associated with a markedly prolonged QT interval, which was treated with b-blockers and a subsequent pacemaker. The mother had a history of “seizures” as a child that had been treated with various medications, which did not appear to affect her events. She continued to have episodes 2 to 3 times a year, and witnesses said she w...
