About Dr Ajita Kanthan, Cardiologist 


Dr Ajita Kanthan (MBBS BMedSc PhD FRACP FCSANZ) completed his undergraduate medical training at the University of Sydney in 2000, following up with specialising in internal medicine and adult cardiology at Westmead Hospital in 2008. In 2013, he earned a Doctor of Philosophy Degree in Medicine, from the University of Sydney.


Today, Dr Ajita Kanthan is probably best-known for his pioneering work in the use of radiation-free procedural techniques. Having performed the first radiation-free transvenous pacemaker implant in Australia. Dr Kanthan also performed the first radiation-free cardiac ablations of both supraventricular and ventricular rhythm disorders in Sydney. 


Dr Kanthan’s work represents a significant breakthrough in terms of patient and staff safety with the majority of procedures previously exposing patients up to the same level of radiation as 500 chest x-rays. By performing the procedure without radiation, this surgery can help reduce risk to the patient both in the moment and afterwards. 


Beyond Dr Kanthan’s pioneering work in pacemakers, he is also a national and international trainer on device implantation, electrophysiology and radiation-free procedural techniques. He practices cardiology at a variety of institutions throughout Sydney. 




Dr Kanthan’s key point of focus is rhythm disorders. Accordingly, he treats all forms of rhythm disorders, including atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Additionally, Dr Kanthan also performs all types of device implants including loop recorders, leadless and traditional pacemakers, subcutaneous and traditional defibrillators and bi-ventricular resynchronisation devices.




Dr Kanthan can currently be consulted at a number of locations across Sydney. He is a visiting medical officer at a number of hospitals, including Blacktown Hospital, Norwest Private Hospital, Westmead Private Hospital and Lakeview Private Hospital. He is also the senior cardiologist for Sonic Health and is a senior lecturer at the Western Sydney University.
