Electrocardiographic imaging (ECGI) is a technique to reconstruct non-invasively the
electrical activity on the heart surface from body-surface potential recordings and geometric …

This study aimed to analyze computational techniques in ECG imaging (ECGI)
reconstruction, focusing on dataset identification, problem-solving, and feature extraction …

T-wave alternans (TWA) is a biomarker for sudden cardiac death prediction, characterized
by subtle variations in the amplitude or morphology of consecutive T-waves in …

Sudden cardiac death causes multiple deaths annually, and T-wave alternans are a reliable
predictor of this fatal event. Detecting alternans is crucial for reducing disease incidence …

In this paper, we propose a new ECG compression method using the fractal technique. The
proposed approaches utilize the fact that ECG signals are a fractal curve. This algorithm …

T-Wave Alternans (TWA) are an indicator of sudden cardiac death risk, and they measure
the differences between consecutive T-waves in Electrocardiogram (ECG) studies. In this …

During the last years, attention and controversy have been present for the first commercially
available equipment being used in Electrocardiographic Imaging (ECGI), a new cardiac …

T-wave Alternans (TWA) measures the differences between consecutive T-waves in
Electrocardiographic (ECG) studies, serving as an index for identifying highrisk sudden …
