How proteins cluster to ensure a regular heartbeatUniversity of Cambridge | Dr Antony Jackson
On the surface of each heart muscle cell are tiny pores, or ion channels. These open and close to let sodium, calcium and potassium ions flow in and out of the cells, and generate the electrical signal that causes the heart to contract and ...

Discovering more about our heartbeat – how calcium is controlled in the heart.University of Oxford | Dr Rebecca-Ann Burton
Each heartbeat is controlled by an electric signal that triggers the movement of calcium ions into the heart muscle cells. The flow of calcium ions in and out of heart muscle cells is fundamental for the control of our heartbeat. When disru...

Can we use low-voltage defibrillation to treat heart rhythm disturbances?King's College London | Dr Martin Bishop
Defibrillation, where strong electrical shocks are applied to the heart, is the only effective therapy against life-threatening heartbeat irregularities (arrhythmias). Despite its success, strong electrical shocks can cause pain, trauma and...

Working out how a faulty gene can cause a cardiac arrestUniversity of Manchester | Dr Luigi Venetucci
A clinical student working with Dr Luigi Venetucci at the University of Manchester is investigating how a faulty gene that makes proteins involved in calcium release within the heart can cause irregular heart rhythms. The researchers are e...

RESEARCH
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...

How zebrafish could help in the quest for new heart drugsUniversity of Birmingham | Professor Attila Sik
Irregular heart rhythms (arrhythmias), greatly increase the risk of sudden death from cardiac arrest – when the heart beat suddenly stops – and the risk of heart attacks and strokes. In 2010 the most common arrhythmia, atrial fibrillation, ...

Ensuring future cardiac stem cell therapies work safely and in tandem with patients’ heart cellsUniversity of Surrey | Dr Patrizia Camelliti
Stem cells show great promise for repairing scarred heart tissue after a heart attack. One option for future therapies is to transplant new heart muscle cells (cardiomyocytes) that have been made from stem cells, onto the damaged area. For ...
