长程口服胺碘酮,对多种室上性心律失常有效。预激综合征伴心房纤颤(房颤)时,快室率可引起血流动力学严重损害或心室纤颤(室颤)。常规抗心律失常药中,许多不能延长副束不应期,必须手术切除副束。而胺碘酮用于预激综合征时,可预防房颤复发,在复发时可减慢心室率;因此,对于那些不愿或不能手术的病人,该药是一个安全、有效的备用药。
Long-term oral amiodarone, effective on a variety of supraventricular arrhythmias. When Wolff-Parkinson-White syndrome (WPW) is accompanied by atrial fibrillation (AF), the rate of fast chamber can cause severe hemodynamic damage or ventricular fibrillation (VF). Conventional antiarrhythmic drugs, many of which can not extend the side-by-side, must be surgically removed. Amiodarone, when used in Wolff-Parkinson’s syndrome, prevents the recurrence of atrial fibrillation and slows the rate of ventricular recurrence; therefore, it is a safe and effective alternative for those who are unwilling or unable to operate.
