Dr Mahajan is interested in all aspects of clinical cardiology and his expertise lies in the management of patients with arrhythmias includes electrophysiology study and catheter ablation and device therapy including pacemakers, defibrillators and cardiac resynchronisation therapies. He has a particular interest in catheter ablation of complex arrhythmias such as atrial fibrillation. Rajiv has had an interest in cardiology and electrophysiology since primary school and continues to enjoy the mental stimulation it provides.
Following his graduation from the University of Delhi in 1997 Rajiv continued his Physician training at the University of Delhi and then Cardiology training at All India Institute of Medical Sciences, New Delhi. He went on to complete a 4-year clinical training in Cardiac Electrophysiology and Pacing at the Royal Adelaide Hospital, Adelaide.
Rajiv has completed a PhD on the role of obesity in atrial fibrillation and furthered his research in the postdoctoral period at the University of Adelaide. The Australian Post Graduate Award and Leo J Mahar Scholarship supported him during his PhD and the National Health and Medical Research Council (NHMRC) and the National Heart Foundation (NHF) provided support during his post-doctoral period. The work from his PhD has provided mechanistic link between obesity and atrial fibrillation and demonstrated that intervention by weight reduction may favourably affect obesity related AF substrate. His excellence in research has been recognised by several awards such as the prestigious Ralph Reader prize, Cardiology Society of Australia and New Zealand (2013) and the Young Investigator Award, Heart Rhythm Society, USA (2013), First prize, Best Oral abstract at the Asia Pacific Heart Rhythm Society (2013), Eric Prystowsky Clinical Research Award, Heart Rhythm Society, USA (2015), Derek Frewin Early Career Researcher Award (2017) and the Young Author Achievement Award, JACC Journals (2018).
He has published widely in peer-reviewed journals and has over 100 publications and several book chapters. Dr Mahajan is interested in research leading to improvement in the management of heart rhythm disorders. He has a particular interest in the modification of its risk factors and interventions aimed at improving outcomes of patients with atrial fibrillation. In addition, he is interested in investigating the potential ways that can reduce the burden of cognitive impairment in atrial fibrillation, supported by The Hospital Research Fund.
He is dedicated to education of patients and doctors in the management of heart rhythm disorders. He is responsible for the establishing the Specialised AF Clinic at the Lyell McEwin Hospital to provide comprehensive care to patients with atrial fibrillation.
Dr Mahajan has recently joined SA Heart and will be consulting regularly from our Ashford and Norwood rooms.
