乙胺碘呋酮为苯呋喃衍化物,是一种含碘的抗心律失常药。最初在欧洲被用作抗心绞痛药,后来证明该药能延长动作电位时间。在人的电生理研究表明,口服乙胺碘呋酮能延长心房肌、房室结、心室肌和异常旁路束的不应期。最近的临床研究证明了该药在各种心律失常(大多数对其它抗心律失常药耐药)中的有益作用。这 Amiodarone is a benzofuran derivative that is an iodine-containing anti-arrhythmic drug. Originally used as an anti-anginal drug in Europe, it was later demonstrated that the drug prolonged action potential time. Electrophysiological studies in humans have shown that oral administration of amiodarone prolongs the refractory period of atrial muscles, atrioventricular nodal and ventricular muscles, and abnormal bypass. Recent clinical studies have demonstrated the beneficial effects of this drug in various arrhythmias, most of which are resistant to other antiarrhythmic drugs. This
