Based on his wide case experience and attention to detail, Dr. Liu has built a reputation for taking on difficult cases and high-risk patients, often achieving successful outcomes in patients who had undergone failed procedures elsewhere, and with an unparalleled safety record - for the high risk cases as well as the simple cases. Just as importantly, Dr. Liu is known for his clear communication skills and warm bedside manner.

Dr. Liu is committed to advancing our understanding of mechanisms of arrhythmias and novel approaches to catheter ablation. He has done work aimed at evaluating the utility of dominant frequency analysis as a method to identify areas of complex fractionated atrial electrograms (CFAEs) in the human left atrium during atrial fibrillation. CFAE areas may be important in sustaining persistent atrial fibrillation and thus have become target for catheter ablation of this arrhythmia. In addition, Dr. Liu is pursuing improvement in the integration of advanced imaging technologies such as intracardiac echocardiography into complex ablation procedures for atrial fribrillation and ventricular tachycardia. Dr. Liu has co-authored several manuscripts in respected cardiology journals, and his recent findings were presented at the Annual Scientific Sessions of the American Heart Association and the Heart Rhythm Society. Dr. Liu has given multiple invited lectures at prominent national and international electrophysiology conferences. He is a member of the Heart Rhythm Society, the American College of Cardiology, and the American Heart Association. He currently serves on the Ethics and Displicine Committee of the American College of Cardiology.
