Abstract
Aim. Blood pressure (BP) determination in atrial fibrillation (AF) patients remains challenging due to its high inter-measurement variability. The novel methodology of precise beat-to-beat BP determination may be used to guide the hypotensive therapy selection and adjustment, but along with that provides additional opportunity for the investigation of hemodynamics in patients with chronic AF. Material and method. The study sample consisted of 60 patients with the main diagnosis of grade II-III arterial hypertension; 30 of those were on sinus rhythm and 30 had chronic non-valvular AF. In all patients HR was within the limits recommended for left ventricular ejection fraction of >40%. Beat-to-beat systolic, diastolic, and pulse BP (SBP, DBP, and PBP, respectively) assessment at each heart beat within 15 minute interval was performed with “Kardiotekhnika-SAKR” system (NAO “Incart”, St.Petersburg, Russia).
