1. A tissue assessment system, comprising:
an assembly comprising at least one electrode, at least one ultrasound transducer, and at least one ultrasound sensor, wherein:
the at least one electrode is configured to determine electrical charge of one or more tissue locations; and
the at least one ultrasound transducer is configured to emit soundwaves in a direction of one or more cardiac chambers and the at least one ultrasound sensor is configured to receive soundwave reflections; and
at least one processing element configured to:
determine anatomical information of a tissue portion of the one or more cardiac chambers from the received soundwave reflections; and
produce an assessment of the tissue portion based on the electrical charge of the one or more tissue locations and the anatomical information,
wherein the assessment comprises an identification of healthy tissue when the electrical activity of the one or more tissue locations is determined to be adequate and the anatomical information is indicative of adequate motion of the tissue portion.
