SIGNIFICANCE OF ORTHOSTATIC REACTIONS OF VENTRICULAR RATE AMONG OTHER CLINICAL AND HEMODYNAMIC SIGNS IN PREDICTORS OF ATRIAL FIBRILLATION CONTROL

Prognostic significance of orthostatic reactions of ventricular rate (OR VR) among other clinical and hemo-dynamic characteristics in patients with permanent atrial fibrillation (AF below) in 123 patients (62 men and 61 women) aged 55 ± 15 years with a prescription AF 6 ± 5 years has been studied. Prognostic signi¬ficance of clinical signs and hemodynamic parameters in assessment of the effectiveness of permanent AF control was determined retrospectively on the medical therapy results via step discriminant analysis. It is established that the type of OR VR together with other clinical and hemodynamic characteristics (body mass index, QRS duration, prescription of AF, the total power spectrum, the sympathetic and vagal balance) has prognostic significance in the effectiveness of control ventricular rate in atrial fibrillation, it is necessary con¬si-der when choosing a treatment strategy for these patients.
