Spencer Rosero is an Associate Professor of Medicine and Director of the Pacemaker Clinic. He also serves as Co-Director of the Hereditary Arrhythmia Clinic of the University of Rochester which is involved in the care of families with hereditary heart rhythm disorders such as Long QT Syndrome, Brugada's Syndrome, ARVD, and Idiopathic Ventricular Fibrillation. He joined the University of Rochester faculty in 2000 and is certified by the American Board of Internal Medicine in Internal Medicine, Cardiovascular Disease, and Clinical Cardiac Electrophysiology and Pacing.

With his colleagues, Drs. Huang, Hall, and Tompkins, Dr. Rosero is an investigator in several clinical research projects. The University of Rochester participated in large multi-center implantable device trials such as Executive Committee of the recently completed Multicenter Automatic Defibrillator Implantation Trial II (MADIT II), COMPANION Trial, and the MIRACLE resynchronization therapy trial. New mapping and ablation catheter investigations as well as antiarrhythmic medication investigations are conducted.
