Cardiac electrophysiology and arrhythmia research at St George’s has a long-standing reputation for excellence.
It has been led for many years by Professor A John Camm with Dr Elijah R Behr, Professor Sanjay Sharma, Professor Marek Malik and Dr Velislav Batchvarov. Added to this are strong academic interests from Honorary Senior Lecturers Dr Mark Gallagher and Dr Magdi Saba.
The focuses are on sudden death, ventricular arrhythmias and atrial fibrillation with a translational approach studying genetics, proteomics, pathology, epidemiology, electrocardiology, drug therapies and interventional techniques.

The research interests in this group are as follows:
- Sudden Arrhythmic Death Syndrome (SADS)
- Monogenic arrhythmic syndromes and cardiomyopathies
- Clinical non-invasive and invasive investigation of atrial fibrillation
- Ventricular and ischaemic heart disease
- Novel drug therapies in atrial fibrillation
- Interventional studies of ventricular arrhythmia research
Within the Arrhythmias & Cardiomyopathy research group we focus on epidemiology, electrocardiology, pathology and genetics of sudden death in various groups, including:
- The general population;
- Young people; and
- Sudden Arrhythmic Death Syndrome (SADS).
We also focus on:
- Clinical and genetic investigation of monogenic arrhythmia syndromes and cardiomyopathies and the acquired long QT syndrome due to medications;
- Novel gene discovery and genetic modifiers of phenotype in monogenic arrhythmia syndromes;
- Clinical non-invasive investigation of atrial fibrillation, ventricular and ischaemic heart disease;
- Major studies of intervention and novel drug therapies in atrial fibrillation;
- Proteomic and functional investigation of atrial fibrillation and heart failure; and
- Interventional studies of ventricular arrhythmia research.

The objectives of the Arrhythmias & Cardiomyopathy research group is to develop novel methods for improving and refining the stratification of risk of sudden death in inherited and acquired cardiac disease and in the general population, utilising clinical and molecular markers.
We also aim to translate these novel risk markers into tools to personalise medical management, and develop novel clinical and genetic diagnostic methods in the inherited heart diseases. Our research will ultimately result in the emergence of novel approaches towards intervention and drug therapies for arrhythmias in inherited and acquired heart disease.
We also aim to evaluate the role of ECG for screening in the prevention of sudden death in the general population and sports people, and evaluate the value of ECG markers of sudden death in patients following myocardial infarction, with cardiomyopathy or heart failure in orer to implement effective therapy with the implantable cardioverter defibrillator.
Another objective is to evaluate the effect of cardiac and non-cardiac drug therapy with regard to it's effect on sudden and all cause cardiovascular death, investigate the risk for patients with atrial fibrillation and to demonstrate appropriate therapy to reduce that risk.
Research into SADs at St George's University of London has contributed directly to the development of the patient pathways and standards required of the assessment of families with SADS deaths and inherited heart disease.
Furthermore, research into drug-induced arrhythmia will be a first step of pharmacogenomic personalisation of drug therapy to reduce the risk of sudden death due to medication.
Epidemiological studies: the ICAP clinic, funded and run by Cardiac Risk in the Young will study 14-year-olds prospectively over five years in the South East of England to establish the potential benefit of ECG screening to prevent sudden death (Professor Sanjay Sharma).
