Anthony Nathan, MD FRCP | Consultant Cardiologist
Arrhythmias, Care of Pacemakers and ICDs, General Cardiology
Dr Anthony Nathan was a consultant cardiologist at St Bartholomew’s Hospital in London where he worked for 30 years, and more recently at Watford General Hospitals. He left the NHS 3 years ago, but is currently an honorary consultant at Watford General. His private office and secretary are based at Spire Bushey Hospital, where he consults. He also works at the Platinum Medical Centre at The Wellington Hospital.
Dr Nathan is trained in clinical cardiology, specialising within interventional electrophysiology, having been involved in this sub-speciality since it started. He looks after all sorts of patients with arrhythmias and also implantable pacemakers and cardiac defibrillators.
Dr Nathan has a major interest in the diagnosis and treatment of coronary disease. He is fully involved in the care of patients with other cardiac problems including hypertension, cardiac failure and so on. He is a Fellow of the Royal College of Physicians in London. He qualified from medical school at the Middlesex Hospital in London in 1975, obtaining his membership of the Royal College of Physicians two years later and Fellowship subsequent to that.
