We report a case of atrial tachycardia in a 60-year-old male 8 years postorthotopic heart transplantation. At electrophysiology study, the clinical rhythm was found to arise from the remnant of the recipient atrium and was successfully terminated by delivery of radiofrequency energy. Surgical scars formed at the anastomosis of the recipient and donor atrium during the time of orthotopic heart transplantation are thought to electrically isolate the two areas. Although rarely recognized, dysrhythmias originating from the recipient atrial remnant may occur more often than previously thought.
我们报告一例60岁男性在原位心脏移植8年后发生房性心动过速的病例。在电生理研究中，发现临床节律起源于受体心房残余部分，并通过射频能量传递成功终止。原位心脏移植时受体与供体心房吻合处形成的手术瘢痕被认为使这两个区域电隔离。尽管很少被认识到，但起源于受体心房残余部分的心律失常可能比以前认为的更常见。
