Academic Bio

Dr Akoum is an Assistant Professor of Medicine at the University of Utah. Dr Akoum studied Mathematics and graduated with a Bachelor of Science from the American University of Beirut in 1997. He subsequently obtained his medical degree in 2001. Dr Akoum completed an Internal Medicine Residency at Indiana University in 2005. He came to Salt Lake City in 2005 to join the Cardiovascular Disease fellowship which he completed in 2008. He went on to pursue and complete his training in Cardiac Electrophysiology in 2009. He was voted by his peers as the Chief Cardiology Fellow in 2008. He was also voted by the faculty as the cardiology fellow of the year the same year. Upon completion of his fellowship training, he was hired to join the faculty in 2009.

Dr Akoum is board certified in Internal Medicine, Cardiovascular Disease and Clinical Cardiac Electrophysiology. He also serves in several teaching and administrative roles including medical student and cardiac electrophysiology fellows training.

Dr Akoum has been involved in clinical and translational research throughout his training. He received the Resident Research Award at Indiana University in 2004. He enrolled and completed a Masters Degree in Clinical Investigation at the University of Utah in 2011. Dr Akoum is a research investigator at the Comprehensive Arrhythmia Research and Management (CARMA) center. He has authored several manuscripts and presented at several national and international meetings where he was a finalist and award recipient at the Northwestern Cardiovascular Young Investigator Forum and the Heart Rhythm Society Young Investigator Competition. His research interests include atrial fibrillation management including catheter ablation and drug treatment as well as the associated thromboembolic risk. He is also interested in management of ventricular arrhythmias and risk assessment of sudden cardiac arrest.
