About me

Janet Tsang, MD, is a non-invasive cardiologist at MedStar Good Samaritan Hospital. She has board certifications in clinical cardiac electrophysiology, cardiovascular disease, nuclear cardiology, adult echocardiography, and internal medicine. She is a Fellow of the American College of Cardiology (FACC) and the Heart Rhythm Society (FHRS).

Dr. Tsang is a specialist in a variety of cardiac issues including coronary artery disease and arrhythmias. Her approach is to treat the whole patient, incorporating each individual’s social, cultural, and lifestyle factors when developing a treatment plan. Dr. Tsang enjoys working with diverse populations and has worked in a wide variety of clinical settings over the years.

When Dr. Tsang first meets with patients, she begins by educating them and takes the time to thoroughly explain their diagnoses and their test results. Once patients understand their condition, Dr. Tsang helps them create an individualized plan to improve their heart health.

“I am constantly learning and adapting to new advancements, knowledge, and techniques that are being developed in my field. As a physician, it is my job to stay abreast of new information so that I can pass that on to my patients and help them make the best choices for their healthcare."

“I believe in practicing medicine in a humanizing way.  Patients are not just their symptoms or test results; they are people with full lives, rich histories, and a variety of social and economic factors that impact their health. Good patient care means understanding the entire context of my patients, so that I can best serve their particular needs and circumstances and work with them to improve their health.”
