Single coronary artery and sick sinus syndrome.
We report 2 patients with recurrent syncope and dizziness, later noted to have single coronary arteries. Both had right heart strain, one having pulmonary hypertension and the other having right ventricular outflow obstruction, which resulted in sinus node dysfunction. Patients were refractory to medical therapy and improved after pacemaker implantation.
