METHOD OF DIAGNOSING DIASTOLIC DYSFUNCTION OF RIGHT VENTRICLE IN PATIENTS WITH CHRONIC PULMONARY HEART Russian patent published in 2013 - IPC A61B8/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, in particular to echocardiography. Degree of spread of tricuspid flow in colour M-modal mode with determination of Tei-index is determined. Pulse-wave tissue Dopplerometry of tricuspid valve ring and interventricular septum during Dopplerechocardiography is additionally carried out. If rate of tricuspid flow spread decreases to 30 cm/sec and lower and Tei-index increases higher than 0.38 in spectrum of tissue Dopplerometry of tricuspid ring diastolic dysfunction of right ventricle in patients with chronic pulmonary heart is diagnosed. In case if rate of tricuspid flow spread decreases to 28-30 cm/sec, Tei-index increases to 0.38-0.61 in spectrum of tissue Dopplerometry of tricuspid ring diastolic dysfunction of right ventricle, accompanied by moderate pulmonary hypertension is diagnosed. In case if rate of tricuspid flow spread decreases to 27 cm/sec and lower and Tei-index increases higher than 0.8 in spectrum of tissue Dopplerometry of tricuspid ring expressed diastolic dysfunction of right ventricle, accompanied by severe pulmonary hypertension is diagnosed. I.

EFFECT: method makes it possible to detect diastolic dysfunction of right ventricle and assess its severity at early stages.
