RHYTHM AND CONDUCTION DISORDERS IN PATIENTS WITH SERONEGATIVE SPONDYLARTHRITIDES. INCIDENCE AND RISK FACTORS

Bogatyreva Valentina Aleksandrovna, Morova Natalia Aleksandrovna

The article presents the results of a study that evaluated the frequency of cardiac arrhythmias and conduction disorders in patients with seronegative spondylarthritis and identified the factors that influenced their development. Materials and methods. The study included 120 patients with seronegative spondylarthritis who were treated at the Rheumatology Department of the Omsk Regional Clinical Hospital. All patients underwent 12-lead electrocardiography and echocardiography. Various rhythm and conduction disorders of the heart were detected in 48 (40%) of the 120 patients. Supraventricular extrasystoles (p = 0.0525) and ventricular extrasystoles (p = 0.0249) were detected significantly more often. Atrioventricular block of grades 1 and 2 was detected in 8.3±2.5% of cases (n=10). The analysis of correlation relationships showed that the duration of the PQ interval depends on the age of the patients (r=0.3, p=0.000526) and the weight of the patients (r=0.3, p=0.000976). Arrhythmia and conduction disorders in patients with CnsSpA were associated with the presence of arterial hypertension.
