Dr Walker has a medical practice in Lindfield on the upper north shore of Sydney. He provides a service in all aspects of echocardiography, focusing on stress echocardiography which is a well accepted, accurate method for assessing heart disease, not involving irradiation or injections. There are presently no other stress echo services on the upper North Shore.

Dr Walker commenced stress echocardiography in 1992 and has since performed 15,000 studies, over 30,000 trans thoracic echoes and 2,000 trans oesophageal echoes. Stress echocardiography provides much more information to the practitioner than stress testing alone.

His other area of expertise is in the field of preventative cardiology and he has also commenced a related service in arterial screening, which is an indirect measure of endothelial function and arterial stiffness, and does not involve irradiation or injections. Dr Walker has published seven books on preventative cardiology and lectures both nationally and internationally on this subject.
