Non-Invasive Imaging of Cardiac Activation and Recovery
TL;DR: The quality of the results and the required computation time permit the application of this inverse procedure in a clinical setting, and the use of initial estimates based on the general electrophysiology of propagation is attributed to.
Journal ArticleDOI
Noninvasive Electrocardiographic Imaging of Arrhythmogenic Substrates in Humans
TL;DR: This review summarizes results from electrocardiographic imaging studies of arrhythmogenic substrates associated with human clinical arrh rhythmias, which include heart failure, myocardial infarction scar, atrial fibrillation, and abnormal ventricular repolarization.

TL;DR: The current status of ECGI validation as well as the major challenges remaining for complete adoption ofECGI in clinical practice are discussed and ‘best’ practices for technical validation are proposed and collaborative efforts recently organized.
Journal ArticleDOI
Imaging the electromechanical activity of the heart in vivo
TL;DR: Electromechanical wave imaging (EWI), a novel ultrasound-based imaging method, is shown to be capable of mapping the electromechanics of all four cardiac chambers at high temporal and spatial resolutions and a precision previously unobtainable in a full cardiac view in both animals and humans.
Journal ArticleDOI
Ultrasound Current Source Density Imaging
TL;DR: In this paper, the authors proposed ultrasound current source density imaging (UCSDI), a direct 3D imaging technique based on a pressure-induced change in resistivity known as the acoustoelectric effect, which is spatially confined to the ultrasound focus.

TL;DR: Image integration with high-resolution 3D CT allows accurate placement of anatomically guided ablation lesions and can facilitate complex ablation strategies and may provide significant advantages for anatomical based procedures such as ablation of atrial fibrillation and nonidiopathic ventricular tachycardia.

A new method for myocardial activation imaging
G. Huiskamp,F. Greensite +1 more
TL;DR: Noninvasive images of the myocardial activation sequence are acquired, based on a new formulation of the inverse problem of electrocardiography in terms of the critical points of the ventricular surface activation map, and it is shown that the method is stable with respect to substantial amounts of correlated noise.

A Noninvasive Imaging Modality for Cardiac Arrhythmias
TL;DR: Electrocardiographic imaging modality ECGI can noninvasively image arrhythmic activation on the epicardium during VT to identify and localize key components of the arrhythmogenic pathway that can be effective targets for antiarrhythmmic intervention.
