Pulse dopplerography examination of the blood flow rate in the large hepatic veins evidenced the possibility of the assessment of the right ventricular failure. Systolic blood flow appeared to be slow in case of sinus rhythm right ventricular failure, while the acceleration of the blood flow occurred in case of atrial fibrillation. Absolute ratio between the maximal rate of the systolic blood flow and the maximal rate of the diastolic flow of the spectrum of Doppler's frequency of pulse dopplerography of large veins in case of the right ventricular failure was lowered irrespective of the pattern of the cardiac rhythm.
