Цель. Оценка влияния сопутствующих заболеваний и аритмического анамнеза на вольтажные характеристики левого предсердия у пациентов с персистирующей фибрилляцией предсердий (ФП).Материал и методы исследования. В исследование было включено 50 пациентов с персистирующей ФП, направленных на первичную радиочастотную аблацию. Всем пациентам выполнялось вольтажное картирование левого предсердия. Вольтажные карты состояли как минимум из 2000 точек, среднее количество точек 2128±104. Области с амплитудой биполярного сигнала 0,1-0,5 мВ относили к области низкого вольтажа (НВ), области с амплитудой биполярного сигнала менее 0,1 мВ расценивали, как область очень низкого вольтажа. Для каждой карты был рассчитан НВ% и процент очень низкого вольтажа.Результаты. Мы выявили статистически значимую заметную корреляцию НВ% с возрастом (p<0,001 r=0,720), женским полом (p=0,016) и длительностью анамнеза на момент старта персистирования (p<0,001, r=0,503). На основании полученных нами данных для прогнозирования НВ% была разработана оригинальная шкала. Шкала включает: возраст, женский пол, длительность аритмического анамнеза на момент старта персистирования. При возрасте более 65 лет присваивался 1 балл, пациентам женского пола присваивался 1 балл, при длительности аритмического анамнеза на момент старта персистирования более 4 месяцев 1 балл, в остальных случаях 0 баллов. Количество баллов по данной шкале показало высокую корреляцию с НВ% (p<0,001 r=0,768). Шкала получила название ВЖД-ритм (Возраст, Женский пол, Длительность анамнеза на момент старта персистирования).Заключение. Возраст, женский пол, и длительность аритмического анамнеза на момент старта персистирования являются предикторами процента сниженного вольтажа левого предсердия у пациентов с персистирующей ФП. Предложенная оригинальная шкала ВЖД-ритм может использоваться для прогнозирования объема сниженного вольтажа у пациентов с персистирующей ФП.

Aim. The aim of the study was to assess the impact of comorbidities and duration of arrhythmic anamnesis on the results of left atrium voltage mapping in patients with persistent atrial fibrillation (AF).Methods. The study enrolled 50 patients who underwent the first radiofrequency ablation of persistent AF. Left atrium endocardial voltage maps were obtained using a 3D electroanatomical mapping system during AF. The voltage maps consisted of at least 2,000 points, with an average of 2,128±104 points. Low-voltage areas (LVA) were defined as <0.5 mV. The percentage of LVA% and very LVA% were calculated. Results. We found a statistically significant correlation of LVA% with age (p<0.001, r=0.720), female sex (p=0.016), and the duration of arrhythmic history at the time of the start of persistence (p<0.001, r=0.503). Based on the data obtained, an original scale was developed to predict LVA%. The scale includes age, female sex, and the duration of arrhythAim.
