ORTHOSTATIC REACTIONS OF VENTRICULAR RATE IN PATIENTS WITH PERMANENT ATRIAL FIBRILLATION

A relationship between different types of orthostatic reactions (OR) of ventricular rate (VR) and clinical ma¬nifestation of permanent atrial fibrillation (AF) in 73 patients (32 men and 41 women) aged (55 ± 15) years with a prescription AF (6 ± 5) years has been studied. All types of OR have been noticed in studied popu-lation. Positive OR of VR have been dominated (41 %), negative and absent OR of VR have been occurred more rarely (34 % and 25 % respectively). Qualified positive OR of VR have been occurred in 27 %, and negative ? 40 % of patients. High incidence of prognostically less favorable qualified negative, positive and absent OR of VR in elderly and senile patients with AF requires closer attention with more precise exami¬na-tion, drug therapy and lifestyle modification of patients.
