BiographyDr. Ellinor is a cardiac electrophysiologist at MGH. His clinical focus is on cardiac arrhythmias and in particular atrial fibrillation and heritable arrhythmias including long QT syndrome, Brugada syndrome and arrhythmogenic right ventricular cardiomyopathy.

Dr. Ellinor attended medical school and graduate school at Stanford University followed by medical internship and residency at Brigham and Women's Hospital. He then came to MGH for his fellowship training in cardiology and cardiac electrophysiology. He joined the faculty in the Cardiac Arrhythmia Service in 2003. Dr. Ellinor is currently an Associate Physician at MGH and an Associate Professor at Harvard Medical School.

ResearchThe goal of Dr. Ellinor's laboratory work is to use genetics to elucidate the molecular basis underlying abnormalities of the heart rhythm and heart function. Much of his recent work has focused atrial fibrillation which is the most common arrhythmia. To identify novel pathways for atrial fibrillation he has used a broad range of techniques including population genetics, electrophysiology, and animal models of arrhythmias.
