Disclosed are devices, systems, and methods for determining the dipole densities on a cardiac surface using electrodes positioned on a torso of a patient. Electrodes are integrated into a piece of clothing worn by a patient. The clothing serves to fix the position of the electrodes adjacent a patient's torso. Ultrasonic transducers and sensors are used to determine a distance between the epicardial surface and the electrodes and are also used to detect epicardial surface motion as well as epicardial wall thickness.L'invention concerne des dispositifs, des systèmes et des procédés de détermination de densités de dipôles sur une surface cardiaque au moyen d'électrodes positionnées sur un torse de patient.
