Abstract

Noninvasive electrocardiographic imaging (ECGi) is a promising tool to provide high-resolution panoramic imaging of cardiac electrical activity noninvasively from body surface potential measurements (“The inverse problem”). This problem is ill-posed, highly sensitive to noise, and can have many (non-physiological) solutions. In order to improve the quality of ECGi signals and extract features for diagnosis, we have developed a torso tank experimental set experimental set up allowing the validation of novel signal analysis tools and improvements to inverse problem algorithm. This set up has so far been used to (i) drive the development and improvement of inverse algorithms, (ii) evaluate the use of ECGi and investigate the underlying mechanisms of different cardiac pathologies including LBBB (for CRT) and major arrhythmias such as ventricular fibrillation.
