In addition to more than 15 years' experience in Cardiology at Consultant level, I have particular specialist interest and expertise in cardiac electrophysiology and ablation of all arrhythmias. I have a particular interest in complex arrhythmias including atrial fibrillation and ventricular tachycardia.
My other areas of experience include pacing, ICD implantation, and cardiac resynchronisation.
I was a member of the writing group for chapter 8 of the National Service Framework on arrhythmias and sudden cardiac death.
I have served as the arrhythmia/devices lead and subsequently the overall cardiovascular clinical lead for the Northwest London Cardiac and Stroke Network.
I was Clinical Lead and Arrhythmia Chair, at the Royal Brompton & Harefield NHS FT between 2006 and 2014.
I have been the Director of the Heart Division of the Royal Brompton Hospital since Dec 2014.

Arrhythmias; Cardiac electrophysiology; Ablation; Pacing (cardiology); Defibrillators; Cardiac resynchronisation
