Most cases of atrial fibrillation are converted with antiarrhythmic medications or external electric defibrillation. However, in some refractory patients, an internal transcatheter defibrillation must be attempted. We report a 50 years old male with an atrial fibrillation of one year duration that was refractory to pharmacological treatment and in whom external cardioversion was unsuccessful. After the application of a bifasic shock of 10 joules between a catheter in the right atrium and another one located at the coronary sinus, the patient was converted to sinus rhythm. At two months of follow up, the patient continues in sinus rhythm.
大多数房颤病例可通过抗心律失常药物或体外电除颤转复。然而，对于一些难治性患者，必须尝试进行体内经导管除颤。我们报告一例50岁男性，房颤持续一年，药物治疗无效，体外电复律也未成功。在右心房导管与位于冠状窦的另一根导管之间施加10焦耳的双相电击后，患者转复为窦性心律。随访两个月时，患者仍维持窦性心律。
