Ramirez, Daniel

F. Daniel Ramirez, MD, is a cardiac electrophysiologist and clinician scientist in the Division of Cardiology at the University of Ottawa Heart Institute. He is also an assistant professor in the Faculty of Medicine at the University of Ottawa.


Dr. Ramirez holds a Bachelor of Science Degree in Biochemistry from the University of Ottawa and an MD from Queen’s University. He completed residencies in internal medicine and cardiology as well as a Master of Science Degree in Epidemiology and a combined clinical and research fellowship in cardiac electrophysiology at the University of Ottawa. He then completed additional training in cardiac electrophysiology as a Banting Postdoctoral Fellow at the Hôpital Cardiologique du Haut-Lévêque and L’Institut de Rythmologie et Modélisation Cardiaque (LIRYC) in Bordeaux, France before returning to Ottawa to join the Heart Institute.

Dr. Ramirez is currently a member of the National Institutes of Health (NIH) Advisory Committee to the Director Working Group on Enhancing Rigor, Transparency, and Translatability in Animal Research.  He was recently appointed to the Editorial Board of the Canadian Journal of Cardiology.

Dr. Ramirez has been awarded the Canadian Institutes of Health Research (CIHR) Banting Postdoctoral Fellowship, Royal College of Physicians and Surgeons of Canada Detweiler Travelling Fellowship, Heart Rhythm Society Travel Scholarship, Cardiac Arrhythmia Network of Canada Discovery Award, Canadian Society for Clinical Investigation/CIHR Excellence in Resident Research Award, and CIHR Frederick Banting & Charles Best Canada Graduate Scholarship (CGS-M), among others. Locally, he has also received the Ottawa Region Cardiovascular Research Trainee of the Year Award and Ernest & Margaret Ford Research Fellowship, as well as the Best Thesis Award for the MSc in epidemiology from the University of Ottawa.

Research and clinical interests

Dr. Ramirez’s research interests focus on the diagnosis and treatment of atrial and ventricular tachyarrhythmias, understanding the impact of percutaneous ablative therapies on cardiac physiology, and improving the predictive ability of translational research.
