Prof. Dr. Koonlawee Nademanee, M.D., is a cardiologist specializing in cardiac arrhythmias and electrophysiology, as well as general cardiology. He completed his medical education at the Faculty of Medicine, Chulalongkorn University, Thailand, earning his M.D. with honors in 1973. He undertook residency training in Internal Medicine at Tulane University and Touro Infirmary in New Orleans, Louisiana, from 1976 to 1978, followed by a cardiology fellowship at the West Los Angeles VA Medical Center in California from 1978 to 1980. His professional credentials include Diplomate certifications from the American Board of Internal Medicine, the American Board of Cardiovascular Disease, and the American Board of Clinical Cardiac Electrophysiology.

Dr. Nademanee is particularly known for his work in the diagnosis and treatment of complex heart rhythm disorders. The supplied biography describes his development and clinical use of mapping techniques involving Complex Fractionated Atrial Electrograms (CFAEs), and the use of CFAE-guided ablation for persistent and paroxysmal atrial fibrillation. His work also includes research into Brugada syndrome and Sudden Unexplained Nocturnal Death Syndrome (SUNDS), including the development of a catheter ablation approach targeting the right ventricular epicardium. The source material also notes his early use of non-invasive CardioInsight vest technology for mapping cardiac arrhythmias.

His academic and leadership experience spans institutions in the United States and Thailand. The provided sources identify him as Director of the Pacific Rim Electrophysiology Research Institute and describe leadership at the Bumrungrad Heart Institute. They also record previous appointments as Professor of Medicine at the University of Southern California and Professor of Medicine and Chief of Cardiology at the University of Colorado. He has been actively involved in clinical research and medical education, has authored or co-authored hundreds of clinical publications, and has served as a reviewer for medical journals. The supplied material reports that he received an honorary doctorate in medicine from Mahidol University in 2005 and the Heart Rhythm Society’s Pioneer in Cardiac Pacing and Electrophysiology Award in 2026. He speaks Thai and English.
