Devices and methods for determination of electrical dipole densities on a cardiac surface

A device that generates a table of dipole densities ν(P′,t) at locations P′ on an epicardial surface of a given heart of a patient at times t, comprising:

• a) a measuring and recording unit that measures and records electric potential data Ve at given positions P proximate the patient's torso surface, wherein the measuring and recording unit further comprises:
• one or more ultrasound transducers adapted to be positioned in contact with the torso surface or sufficiently proximate to emit a monitorable signal, the one or more ultrasound transducers being configured to emit waves toward the epicardial surface;
• one or more ultrasound sensors adapted to be positioned in contact with the torso surface or sufficiently proximate to detect a monitorable signal, the one or more ultrasound sensors being configured to receive reflections of the waves from the epicardial surface and produce sensor data;
• an array of multiple electrodes adapted to be positioned in contact with the torso surface or sufficiently proximate to sense the electric potential data Ve;
• at least one probe electrode configured to be positioned within a chamber of the patient's heart configured to record intracardial potential data;
• at least one wearable garment comprising at least one of the multiple electrodes, at least one of the one or more ultrasound transducers, and at least one of the one or more ultrasound sensors;
• and
• b) a processor that is configured to:
• receive sensor data from the one or more ultrasound sensors included with the wearable garment and generate distance measurements from the epicardial surface;
• and
• generate the table of dipole densities ν(P′,t) at locations P′ on the epicardial surface of the heart of the patient at time t, wherein the table is based on the recorded electric potential data Ve, the intracardial potential data, and the distance measurements generated by the one or more ultrasound sensors.
