Identification of the earliest activation area is a common task in focal tachycardia catheter ablation treatments. In these procedures the detection of the electrogram (EGM) activation onset during electroanatomical mapping (EAM) helps to define the ablation target area. However, EAM systems do not automatically detect the EGM activation onset and this is(More)
The electrical activation of the heart is a complex physiological process that is essential for the understanding of several cardiac dysfunctions, such as ventricular tachycardia (VT). Nowadays, patient-specific activation times on ventricular chambers can be estimated from electro-anatomical maps, providing crucial information to clinicians for guiding(More)
Electroanatomical mapping (EAM) systems are commonly used in clinical practice for guiding catheter ablation treatments of common arrhythmias. In focal tachycardias, the ablation target is defined by locating the earliest activation area determined by the joint analysis of electrogram (EGM) signals at different sites. However, this is currently a manual(More)
Integration of electrical and structural information for scar characterization in the left ventricle (LV) is a crucial step to better guide radio-frequency ablation therapies, which are usually performed in complex ventricular tachycardia (VT) cases. This integration requires finding a common representation where to map the electrical information from the(More)
Activation mapping using electroanatomical mapping (EAM) systems helps to guide catheter ablation treatment of common arrhythmias. In focal tachycardias, the earliest activation area becomes the ablation target. Recently, we proposed a single-point wavelet-based algorithm to automatically identify electrogram (EGM) activation onsets for activation mapping.(More)
