ORTHOSTATIC REACTIONS OF VENTRICULAR RATE IN MEDICAL CONTROL OF PERMANENT ATRIAL FIBRILLATION

Article is devoted to studying the Significance of orthostatic reactions of ventricular rate (OR VR) in the clinical course of permanent atrial fibrillation (AF) to improve the effectiveness of its control. It was found that among patients with AF there are all 3 types of OR VR as during sinus rhythm, positive OR VR predo-minate over negative and absent. It was shown, that positive OR are favorable to reduce the severity of symptoms of AF, according to European Heart Rhythm Association (EHRA), less favorable ? absent, and unfavorable ? negative OR VR. It was established, that the control of AF with by beta adrenergic anta-gonists (BAA) is possible in any type of OR VR except qualified positive, combination of BAA and amioda-rone ? for BAA inefficiency, and control of AF with amiodarone is preferable in qualified positive and ne-gative OR VR and when there are contraindications to BAA.
