正常的窦性心律对于心房纤颤病人来说,希望通常是渺茫的,尤其是当药物和心脏电复律除颤无效时。然而,Barnes 医院的心胸外科主任Cox 发明的心脏“迷宫”术,使这一疑难病有所突破,给这样的病人带来希望。将动物和人对照实验的心电活动图用计算机处理后显示:心房颤动是以6条粗大的循环通路为特征。心电活动图提示:如果所有潜在的心房再生环路被切断,手术就有可能成功。因此,“迷宫”术实际上等于用外科手段在心脏置入电路阻断器。在左右心房切一小口,防御电循环导致心房纤颤的发展和
Normal sinus rhythm for atrial fibrillation patients, the hope is usually slim, especially when drug and cardioversion defibrillation invalid. However, cardiac “maze” surgery invented by Cox, director of cardiothoracic surgery at Barnes Hospital, has led to a breakthrough in this difficult disease and brought hope to such patients. Computer-based ECGs of animal and human control experiments showed that atrial fibrillation was characterized by six gross circulatory pathways. ECG activity diagram Tip: Surgery may be successful if all potential atrial regeneration circuits are severed. Therefore, “maze” surgery is actually equivalent to surgically placed circuit blockers in the heart. A small cut in the left atrium to prevent the electrical cycle leading to the development of atrial fibrillation and
