Abstract：【Objective】To investigate the clinical treatment and efficacy of ibutilide in patients with pre-excitation syndrome and atrial fibrillation. 【Methods】The diagnostic criteria of ECG for pre-excitation syndrome with atrial fibrillation are: rapid ventricular rate, absolute RR interval, wide QRS complex with initial delta wave. A retrospective analysis of the clinical data and treatment measures of 7 patients with pre-excitation syndrome and atrial fibrillation in Guangzhou First People's Hospital from February 2017 to June 2019. All patients were treated with Ibutilide fumarate injection. After the medication, all patients received pre-excitation of the side channel and (or) radiofrequency ablation of atrial fibrillation. Patients' sinus rhythm cardioversion and surgery after medication were recorded. 【Results】All 7 patients had good curative effect after intravenous injection of ibutilide, which could effectively convert pre-excitation syndrome patients with atrial fibrillation to sinus rhythm and reduce ventricular rate. In brief, 5 cases were converted to sinus heart rate, 1 case had a lower ventricular rate than before treatment, 1 case had no significant change in ventricular rate after amiodarone treatment and electrical cardioversion failed. However, the ventricular rate decreased significantly after ibutilide treatment. All patients were successfully treated with pre-excited side channel and/or radiofrequency ablation of atrial fibrillation.【Conclusion】Ibutilide can effectively convert the heart rhythm of patients with pre-excitation combined with atrial fibrillation, and can effectively reduce the ventricular rate of patients with pre-excitation combined with atrial fibrillation, which is beneficial to subsequent radiofrequency ablation treatment.
