ANS dysfunction, known as dysautonomia, can lead to many clinical manifestations, some of them severe and debilitating. Dysautonomia is often underdiagnosed and detected at late stages, due to its wide phenotypic variability and the poor familiarity of the physicians with the disease, leading to higher cardiovascular mortality and morbidity. The diagnostic and prognostic potential of nuclear cardiology in the assessment […]
