Изобретение относитс к области мед$ цикы .This invention relates to the field of honey.
Известен способ диагностики приобретенных пороков сердца, заключающийс в сравнении спектра фонокардиосиг ала с клинической симптоматикой 1.A known method for the diagnosis of acquired heart disease, which consists in comparing the spectrum of phonocardiosygla with clinical symptoms 1.
Однако известный способ не обеспечивает точной диагностики аортальной недостаточности на фоне митрального порока.However, the known method does not provide an accurate diagnosis of aortic insufficiency on the background of mitral defect.
Целью изобретени вл етс инструментельна диагностика аортальной недостаточности на фоне митрального порока.The aim of the invention is an instrumental diagnosis of aortic insufficiency against the background of mitral defect.
Это достигаетс тем, что определ ют степень отклонени спектра протодиастоли- ческого шума фонокардиосигнала от эталонного спектра при митральном и комбинированном митрально-аортальном пороке.This is achieved by determining the degree of deviation of the spectrum of the protodiastolic noise of the phonocardiosignal signal from the reference spectrum during mitral and combined mitral-aortic defect.
На фиг. 1 изображены эталонные спект рограмМы участка протодиастолическогоFIG. 1 shows reference spectrograms of the proto-diastolic segment.

Пример. На больного накладывают датчики фонокардиосигнапов (ФКС), электрокардиосигналов (ЭКС) и электросфиомосигналов (ЭСС) сонной артерии и выдел ют участок протодиастолического шума . Определ ют амплитудный частотный спектр ФКС выделенного участка протоди столического шума (полученную спектрограмму см. на фиг. 2). Интенсивность высокочастотных составл ющих (пор дка 2500Гц) 48 дб, а интенсивность низкочастотных составл ющих : (пор дка 60 Гц) 64,2 дб. Сравнивают полученные данньш с эталонными спектрограммами, перенесенными с фиг. 1. В св зи с тем, что спектрограмма больного лежит р непосредственной близости от эталонной спектрограммы (а), соответствующей митральному стенозу, делают заключение о наличии у больного митрального стеноза.Example. The patient is implanted with sensors of phonocardiosignal (FCC), electrocardiograms (ECS) and electrofiomosignals (ESS) of the carotid artery, and a section of protodiastolic noise is isolated. The amplitude frequency spectrum of the FCC is determined for a selected section of the protodolic noise (the spectrogram obtained in Fig. 2 is obtained). The intensity of the high-frequency components (on the order of 2500 Hz) is 48 dB, and the intensity of the low-frequency components: (on the order of 60 Hz) 64.2 dB. The obtained data are compared with the reference spectrograms transferred from FIG. 1. Due to the fact that the spectrogram of the patient lies in close proximity to the reference spectrogram (a) corresponding to mitral stenosis, a conclusion is made that the patient has mitral stenosis.
