A clinical trial testing what level of potassium supplements are beneficial after heart surgeryQueen Mary, University of London | Professor Dr Benjamin O'Brien
Many people who have heart surgery go on to experience abnormal heart rhythms, particularly atrial fibrillation (AF), which can increase the risk of a blood clot forming inside the heart. It is thought that low levels of potassium in th...

Invisible insulin resistance linked to increased risk of sudden death
Years before developing diabetes, people with insulin resistance could be more likely to develop abnormal heart rhythms, which may put them at greater risk of sudden death, according to research we've funded and presented today at the British Cardiovascular Society conference.

Fixing the heart’s electrical wiring system to prevent abnormal heart rhythms and heart failureUniversity of Manchester | Dr Halina Dobrzynski
The heart has an electrical wiring system called the ‘cardiac conduction system’ (CCS), which is responsible for the start and coordination of each heartbeat. When this system goes wrong it results in a slow heart rate – a type of arrhythmi...

Revealing why heart attacks can trigger abnormal heart rhythms or heart failureUniversity of Manchester | Professor Andrew Trafford
Professor Andrew Trafford and his colleagues at the University of Manchester are working out what factors within cells are responsible for triggering irregular heart rhythms, or arrhythmias. People who have had a recent heart attack are, i...

Developing a realistic computer model of abnormal heart rhythmsImperial College London | Dr Emmanuel Dupont
Dr Emmanuel Dupont and his team at Imperial College London are testing a new computer simulation, which would allow researchers to study abnormal heart rhythms. To beat regularly, the heart contracts in response to complex electrical ci...

Improving outcomes for people with aortic stenosis and damaged heart muscleUniversity College London | Dr Thomas Treibel
The aortic valve controls blood flow from the heart into the body’s main artery: the aorta. Aortic stenosis is the narrowing of this valve. In severe cases, surgery is needed to replace it. Around half of people with severe aortic stenosis ...

Studying the proteins that control heart rhythmUniversity of Oxford | Professor Ming Lei
Tiny pores, or ion channels on the surface of heart muscle cells open and close to let electrically charged sodium, calcium and potassium ions flow into and out of heart cells and generate the electrical signal that spreads from the top of ...

Understanding how faulty ion channels cause abnormal electrical activity in the heartUniversity of Bristol | Professor Jules Hancox
An arrhythmia is an irregular heartbeat caused by disorganized electrical signals in the heart. Arrhythmias can be fatal and they are a major cause of sudden cardiac death. The production and flow of electricity through the heart muscl...
