[Nuclear stethoscopy. The clinical technic, methods and applications]

The paper reports on a new way of cardiological, radionuclidic investigation of the patients, a technique used for the first time in Romania. The technique and investigation method are presented in detail, with emphasis on some more important stages. As resulting from the description of the methodology, the performances of the left ventricle consist of three types of radioactivity/time curves at: first passage, beat by beat, and their summation. Of the advantages offered by the nuclear stethoscope, mention should be made that, besides the evaluation of systolic and diastolic parameters, it monitors the left ventricle functions in the rhythm disturbances, beat by beat, and being mobile, it permits the investigation at the patient's bed. Finally, the paper presents several cases investigated by the authors, and their special clinical applicability.
