Professor Alan John Camm - Professor of Cardiology (QHP., MD., F.R.C.P., F.E.S.C., F.A.C.C.)

Professor Camm studied medicine at Guy's Hospital Medical School, London. After qualifying in 1971 he worked at Guy'sHospital for three years and then spent a year in Vermont, USA before working at St. Bartholomew's Hospital in London, where he spent 12 years. He was then elected the Chairman of Medicine in October 1990.

Professor Camm is a Fellow of The Royal College of Physicians and also a Fellow of the American College of Cardiology, the American Heart Association, the Council of Geriatric Cardiology and the European Society of Cardiology. He is also a member of the British Cardiac Society, the British Pacing and Electrophysiology Group and the North American Society of Pacing and Electrophysiology.

Professor Camm has a broad range of professional interests. His major speciality is cardiac arrhythmias but he is also much involved in clinical cardiac electrophysiology, cardiac pacemakers, risk stratification in post myocardial infarction, heart failure and cardiomyopathy drugs. Professor Camm has given over 1000 lectures to international audiences, written more than 822 papers and appears in over 1193 abstracts. Professor Camm is widely recognised for his research and teaching roles at national and international levels.

In partnership with Richmond Pharmacology, Professor Camm's group, based within St. George's University of London, offer clients two main approaches in QT interval measurement and analysis:

manual over-read by cardiologists
semi-automated method with cardiologist verification

In fully manual over-read the QT interval is measured by a highly trained and experienced cardiologist on screen using electronic callipers (MUSE CV Interval Editor, GE Marquette Medical Systems) with sufficient magnification allowing the measurement precision equal to the storage frequency of 500 MHz, i.e. 1 ms. Whilst the details of the analysis can be discussed and agreed with our clients at the study design stage, as a matter of routine, in each ECG the QT interval is measured in all 12 leads. The median QT interval of all measurable beats from the 12 leads is then taken as valid for that particular ECG.

Alternatively, if this better suits client's needs we also offer regulatory compliant semi-automated QT interval measurements. In this method, interval markers derived by MUSE CV Interval Editor are assessed for accuracy by an experienced and fully trained cardiologist. The degree of cardiologist input may vary to meet the client needs.
