Dr. Gary Lee Chin Keong is a Consultant Cardiologist and Electrophysiologist, primarily dealing with coronary artery and arrhythmia (abnormal heart rhythm) diseases related to the heart. His areas of specialty include interventional cardiology (coronary angiogram and angioplasty), electrophysiology study and radiofrequency ablation, cryoablation, cardiac implantable electronic devices implantation, cardiac diagnostic procedures such as echocardiography, tilt-table test, diagnostic cardiac rhythm monitoring, cardiac stress test (exercise stress test and stress echocardiography) and coronary CT angiography.

He has special interest in complex arrhythmias ablation using advanced 3D cardiac mapping system as well as cardiac resynchronization therapy. Over the course of his career, he has been actively involved in the training of doctors in the field of internal medicine and cardiology, in national and regional level. In pursuit of excellence, he has also participated in many international multi-centres trials as investigator, as well as being part of the writing committee and reviewer of national guideline, registry and advisory board.
