I am a cardiologist. In my medical professional career, I have collected the experiences from general practitioner, internal medicine, cardiology and sub-specialty in almost all fields of cardiovascular disease; general cardiology, echocardiographer, heart failure, adult congenital heart, and interventional cardiologist. From my wide range of experiences, I can pick what is the best for my patient. Finally, I hope I can share my knowledge and experience in medical, especially cardiovascular society.
