The aim of this paper is to study the relationship between ametropia and propranolol and the reduction of blood pressure in atrial pacing and to shorten the time to correct sinus node recovery.Methods: 10 patients with syncope and syncope precursors, aged from 23 to 62 years old, by radionuclide scan, cardiac catheterization and echocardiography confirmed that all patients with normal function of the left ventricle and the sinus node.Application of atropine, propranolol no anti-indications.Surgeon before the trial affect the sinoatrial Results of functional drugs 48 hours under local anesthesia with a No. 6 quadrupole catheter inserted from the lower extremity vein
