АНАЛИЗ ОСЛОЖНЕНИЙ И ОСОБЕННОСТИ КОРОНАРНОГО КРОВОСНАБЖЕНИЯ У ПАЦИЕНТОВ С СИНДРОМОМ СЛАБОСТИ СИНУСОВОГО УЗЛА И ИМПЛАНТИРОВАННЫМ ЭЛЕКТРОКАРДИОСТИМУЛЯТОРОМ

Sick sinus syndrome (SSS) is a relatively seldom disease characterized by symptoms of tissue hypoperfusion and manifestations on the electrocardiogram. During implantation in the long-term period surgical complications may develop. Features of coronary blood supply are also of great interest. The aim of the study was to analyze surgical complications in patients with SSS and implantd pacemakers, living in the Republic of Bashkortostan.In these patients (n = 61) we analyzed surgical complications over 39,7±0,8 months. In some patients (n=156) features of blood supply were analyzed. After the pacemaker’s implantation complications were found in 10,4% of cases, most often hematoma pocket pacemaker (n=18, 2.9%), pacemaker syndrome (n=10, 1.6 %), pacemaker dysfunction (n=9, 1.4 %) and pacemaker pressure ulcers (n=8, 1.3 %) were registered. During pacemaker implantation according to the type of stimulation complications occurred more often in in VVI - 9.9 % and in DDD stimulation - 9.3 % of cases, less frequently in AAI - 8.8 %. CAG revealed left artery descendens (LAD) stenosis in 32.1% of causes, right coronary artery (RCA) in 26.3%, CA in 21.2% and RCA trunk in 5.1%. In bradycardia LAD were more often stenosed (36.33 %), sinoatrial block II - LAD and RCA (6.33%), sinoatrial block III degree and node failure - LAD and RCA (9.36%).Thus, it was established, that after the pacemaker’s implantation complications were found most often in VVI stimulation and CAG revealed left artery descendens stenosis in most cases.
