About me

Susan O'Donoghue, MD, is a board-certified cardiac electrophysiologist at MedStar Heart & Vascular Institute at MedStar Washington Hospital Center. She previously served as Associate Director of the Cardiac Arrhythmia Center and Director of the Combined Cardiac Electrophysiology Fellowship Program at MedStar Georgetown University Hospital/MedStar Washington Hospital Center. She is presently Director of Cardiogenetic Services at MedStar Washington Hospital Center, a new program for the diagnosis and treatment of inherited cardiac disorders, which she developed. Dr. O'Donoghue has been providing care for more than 25 years.

Dr. O'Donoghue is a member of the Washington Electrophysiologic Society, the Heart Rhythm Society (HRS), and the American College of Cardiology (ACC). She has authored numerous textbook chapters and journal articles.

Dr. O'Donoghue specializes in treating heart rhythm disorders through the use of electrophysiologic studies, catheter ablation procedures and devices such as pacemakers or implantable cardioverter defibrillators (ICD). She is currently conducting research measuring the energy present on the skin surface when an internal defibrillator fires.

Dr. O'Donoghue completed her undergraduate studies in the Honors program at the University of Connecticut, where she graduated summa cum laude and received her medical degree from Georgetown University School of Medicine. She completed her internship and residency training in internal medicine at Emory University, and her Cardiology Fellowship at Emory University and MedStar Washington Hospital Center. Dr. O'Donoghue also completed a fellowship in cardiac electrophysiology and pacing at the MedStar Washington Hospital Center.

Philosophy of Care

"From a young age, I began volunteering at a nursing home. I volunteered until I was hired as a nurse's aide at the age of 16 and continued this work while completing my undergraduate degree. I still remember many of my patients to this day. Together with my love of science, that early experience helped me come to the decision to become a physician

It is an honor to participate in an individual's care. Each person I meet receives my full attention and a unique approach to their diagnosis and treatment plan. I strive to be a patient and empathetic listener, especially when it comes to the concerns of my patients. I feel fulfilled when my patients tell me that they're glad they came to see me and that they would recommend their loved ones to me.

Referring physicians should know that I will communicate clearly back to them and maintain a dialogue. I will take excellent care of their patients."
