[Status of the peripheral circulation in patients with ischemic heart disease with the tachysystolic form of atrial fibrillation according to data of bipolar rheovasography].
In order to analyze peripheral circulation in coronary disease (CD) patients with tachysystolic atrial fibrillation (TAF), as many as 108 patients were examined. Based on the magnitudes of the cardiac index and the pressure of left ventricle filling the patients were distributed into 5 groups depending on the variant (hypovolemic, hypokinetic, hypervolemic, normokinetic, and hyperkinetic) of the TAF dynamics. Twenty-two CD patients with sinus tachycardia and 28 persons without any cardiovascular pathology were also examined. All the examinees were exposed to longitudinal bipolar rheovasography (RVG) of the legs. The most pronounced changes in the blood flow in the lower limbs manifested by the lowest magnitudes of the pulse blood content, circulation intensity, velocity of the systolic inflow, and the highest tone of the peripheral arteries were recorded in patients with the hypovolemic and hypokinetic patterns of the TAF hemodynamics. The peripheral circulatory disorders correlated well with the degree of circulatory failure and with the incidence of the clinical manifestations of microcirculatory abnormalities. At the same time the RVG readings in patients with the hyperkinetic, normokinetic, and hypervolemic variants of the hemodynamics and in those with sinus tachycardia appeared to be similar. The relationship was also established between the time of pulse wave spreading and the degree of circulatory failure, atherosclerosis of the peripheral arteries and the degree of the reduction in stroke volumes because of variations in the duration of cardiac cycles. Antiarrhythmic treatment favoured the improvement of the RVG readings both in cases where the rhythm became rarer and where the sinus rhythm got recovered.(ABSTRACT TRUNCATED AT 250 WORDS)
