ORTHOSTATIC REACTIONS OF DIASTOLIC BLOOD PRESSURE IN PATIENTS WITH PERMANENT FORM OF ATRIAL FIBRILLATION

A relationship between different types of orthostatic reactions (OR) of diastolic blood pressure (DBP) and clinical manifestation of permanent form of atrial fibrillation (AF) in 73 patients aged 68,9 ± 9,3 years has been studied. All types of OR of SBP have been noticed in studied population. Hypotensive (40 %) and isotensive (38 %) OR of DBP have been dominanted, hypertensive OR of DBP have been met rarely (22 %). 3 % of patients had qualified hypotensive OR of DBP, suchlike hypertensive OR haven't been met in our stu-dy. Hypotensive OR of DBP have been more frequently met in elderly people with severe arterial hyper-tension and ejection fraction less then 40 %, isotensive ? in old-aged patients with mild arterial hypertension.
