Đặc điểm lâm sàng, điện sinh lý học tim ở bệnh nhân hội chứng Wolff – Parkinson – White có cơn rung nhĩ

To describe the clinical and electrophysiological c-haracteristics of patients with WPW syndrome with atrial fibrillation and to compare the clinical and electrophysiological c-haracteristics of patients with Wolff - Parkinson - White with and without fibrillation. atrium. Methods: The study was conducted in 49 subjects, including 18 patients with atrial fibrillation in clinical or electrophysiological studies and 31 patients with Wolff - Parkinson - White syndrome. The patients were se-lected in accordance with the study requirements. Research results: The study showed that in the group of atrial fibrillation in WPW syndrome: common age was 49.2 ± 15.6 years old, male accounted for a high rate of 83.3%, cardiovascular disease group was associated with hypertension, functional Sinus node function and intracardiac conduction were normal, the refractory time of the accessory pathway was short, forward 247.7 ± 29.0, retrograde 279.0 ± 24.0 P<0.05. An accessory pathway and a right-sided location were common in the group with atrial fibrillation. Conclusions: Male sex, comorbidities with hypertension, hyperthyroidism, and short refractory duration of accessory conduction pathways may be factors that may influence the occurrence of atrial fibrillation in WPW syndrome.
