We report on a case of significant exertional symptoms secondary to occlusion of a nondominant right coronary artery proximal to the sino-atrial branch, with associated exercise-induced sinus node dysfunction. Successful angioplasty of the occluded right coronary artery restored a normal functional capacity and sinus tachycardia response to exercise.
我们报告一例因非优势型右冠状动脉在窦房结分支近端闭塞继发严重劳力性症状，并伴有运动诱发的窦房结功能障碍的病例。对闭塞的右冠状动脉成功进行血管成形术恢复了正常的功能能力以及运动时的窦性心动过速反应。
