About Dr. Calvin Hsieh

  • Dr. Calvin Hsieh is a highly qualified and experienced cardiologist with an impressive academic and professional background. He graduated from the University of New South Wales with honours before completing his post-graduate training at the cardiac unit at Westmead Hospital in NSW. Under the mentorship of Prof David Ross, a pioneer in electrophysiology in Australia, Dr. Hsieh gained valuable experience in cardiac electrophysiology.

    Dr. Hsieh went on to complete further training in electrophysiology at the Freeman Hospital in the UK, a quaternary referral centre for complex arrhythmia treatment. During this time, he was exposed to the latest technologies and techniques that were beyond what was available in Australia.

    Dr. Hsieh's passion for electrophysiology extends beyond patient care. He is committed to educating other doctors in clinical electrophysiology and is an international proctor for some specialised procedures. With his extensive knowledge and expertise, Dr. Hsieh is a leader in his field and is dedicated to providing the highest level of care to his patients.

  • Dr. Hsieh's commitment to innovation and research has been a driving force in his career. Following his post-graduate training, he dedicated years to investigating the development of, and potential prevention of dangerous ventricular arrhythmias following heart attacks.

    His groundbreaking research earned him the prestigious Ralph Reader Prize, the highest research prize in cardiology in Australia and New Zealand.

    Today, Dr. Hsieh continues to push the boundaries of electrophysiology. He has been named an inventor for a patent related to the field, further cementing his reputation as a leader in the industry. Dr. Hsieh also serves as the Medical Director for CathRx, the only Australian R&D company dedicated to electrophysiology.
