Неинвазивное электрокардиографическое картирование желудочковых нарушений ритма сердца

Неинвазивное электрокардиографическое картирование желудочковых нарушений ритма сердца

Abstract

Цель исследования: сравнить точность неинвазивной топической диагностики желудочковых аритмий на основе результатов неинвазивного картирования и данных внутрисердечного электрофизиологического исследования (ЭФИ). Был обследован 81 пациент (30 мужчин и 51 женщина) в возрасте от 20 до 67 лет (средний возраст 43,5 года) с желудочковой экстрасистолией (ЖЭС) различной этиологии и локализации. Всем пациентам проводилось неинвазивное ЭФИ сердца с использованием программно-аппаратного комплекса "Амикард", затем внутрисердечное ЭФИ и радиочастотная аблация (РЧА) желудочковых нарушений ритмов сердца (НРС). При сравнении результатов неинвазивного и внутрисердечного ЭФИ в 73 случаях было совпадение локализаций аритмогенного фокуса, в 8 случаях документированы расхождения. Таким образом, точность метода для топической диагностики ЖЭС составляла 90,12%.

The aim of this study was to test the accuracy of the noninvasively obtained ventricular activation as compared with that of standard invasive mapping in patients with ventricular arrhythmias. A total of 81 patients (30 male and 51 female) aged 20 to 67 years (mean age of 43.5 years) with ventricular arrhythmias of different localization and etiology were examined. All patients underwent noninvasive electrophysiologic examination, which was performed with Amycard System and subsequent intracardiac mapping and radiofrequency catheter ablation. Comparison of data from the noninvasive and intracardiac electrophysiology studies showed identical localization of the arrhythmogenic foci in 73 cases; discordant results were documented in 8 patients. Thereby, the accuracy of the noninvasive mapping in patients with arrhythmias was 90.12%.
