Clinical Interests

My clinical interest spans all of cardiac electrophysiology, dealing with slow and fast heart rhythm problems.  My clinical expertise includes all cardiac device implantations related to heart rhythm disturbances, as well as a comprehensive list of cardiac ablations (cauterization) to improve or cure arrhythmias occurring in both the top and bottom parts of the heart (including atrial fibrillation and ventricular tachycardias).

*Dr. Sung and his team are the best.

National Jewish Health PatientJune, 2021
Excellent grasp of my concerns. His instructions for tracking oxygen levels & heart rate during exercise probably solved the issue.

all dr/nurses took the time to explain all the tests [my wife] had done. i have no doubt that had we not come to NJH we would not have found out what her medical problems were.

Loved *Dr. Sung! I've already recommended him. He was supportive of my KETO diet and was going to recommend it possibly to some patients. Most doctors disregard it or don't know much about it.
