[The dynamic echocardiographic indices after restoration of the sinus rhythm in patients with the compensated type of atrial fibrillation].

The authors observed 19 patients with paroxysmal atrial fibrillation (AF) and compensatory intracardiac hemodynamics accounting for 10% of all their examinees with AF. Following the retaining of sinus rhythm with the help of lanicor, nitrosorbide and lasix patients of group 1 exhibited increased Vs, Vd, Vcf, EF against decreased left atrial size and left atrial index. Patients of groups 2 and 3 in whom the conversion of sinus rhythm occurred due to guanidine or electric impulses, respectively, the above indices changed insignificantly. These patients had depression of left ventricular contractility, increased end-systolic volume, slowing of Vs, Vcf against slight enhancement of left ventricular pump capacity.
