Resolution of exercise intolerance secondary to ischemic sinus node dysfunction following percutaneous transluminal angioplasty.
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.
