FUNCTIONAL BLOOD CIRCULATION VALUES IN PATIENTS WITH IMPLANTED PACEMAKERS IN THE FIRST SIX MONTHS OF PERMANENT PACING IN DIFFERENT STIMULATED QRS COMPLEX DURATION CLASSES

Abstract

In the department of ultrasound, clinical and instrumental diagnosis and minimally invasive technologies 100 patients (46 – women, 54 – men) who underwent permanent pacemaker therapy were examined. The average age was 69 ± 7 years. The indications for pacemaker implantation were: atrio-ventricular block of varying degrees – 66 people (60 %), sick sinus syndrome – 34 patients (30 %). Patients were divided to three classes of QRS complex duration in accordance with Haghjoo M. et al.: 1 – under 119 ms (normal), 2 − 120-149 ms (extended) and more than 150 ms (significantly extended). Permanent pacing with medical support in the first 6 months results in the elimination bradyarrhythmia rhythm disorders without significant changes of functional blood circulation values with systolic blood pressure increase only. Standard antihypertensive therapy consisting of medical support in patients with implanted pacemaker is sufficient to control systolic blood pressure in patients in classes 1 and 2 and insufficient – in class 3 of QRS complex duration. Patients with implanted pacemaker in 3 QRS complex duration class require intensification of antihypertensive therapy.
