Also available for:

Virtual consultations:

I am trained in all aspects of general cardiology, including the management of chest pain, heart failure and palpitations and have a major subspecialist interest in arrhythmias (heart rhythm disorders) and implantable cardiac devices. I perform catheter ablation for all arrhythmias, including supraventricular tachycardia (SVT), atrial flutter, atrial fibrillation and ventricular tachycardia. I also implant pacemakers, defibrillators and cardiac resynchronisation devices and am an accredited cardiac device specialist.

I am a consultant cardiologist and the lead for cardiac electrophysiology in the NHS at Watford General Hospital, Herts. I am also an honorary consultant at Imperial College Healthcare, Hammersmith Hospital in London. My secretary is based at Spire Bushey Hospital, and my main private practice is based at Spire Bushey Hospital.

I graduated from Guys’, King’s and St. Thomas’ Medical School with distinctions, having already received an intercalated BSc in pharmacology. I am a member of the Royal College of Physicians and have a PhD in cardiac electrophysiology, Imperial College, London. My research findings have resulted in a major multicentre clinical trial in ventricular tachycardia ablation as well as the development and investigation of a novel 3D mapping system for ablation of complex arrhythmias. I continue to pursue my research interests at Imperial College Healthcare. I undertook my postgraduate training in London, having been a trainee at Watford General as well as St. Mary’s and Hammersmith Hospital. During my training years, I have also gained experience at the prestigious Harvard Medical School associated Brigham and Women’s Hospital, Boston, USA.
