Developing a new algorithm to detect arrhythmias and prevent sudden cardiac deathImperial College London | Dr Zachary Whinnett
An arrhythmia is an abnormal heart rhythm. Implantable cardioverter defibrillators (ICDs) are small devices placed within the body that prevent sudden cardiac death by treating life-threatening ‘ventricular’ arrhythmias. If an ICD detects a...

How do faults in the calmodulin gene cause dangerous arrhythmias?University of Liverpool | Dr Nordine Helassa
Many heart conditions run in families because they are caused by a fault or variation in our genetic code that is inherited through the generations. Some genetic faults increase the risk of developing irregular heartbeats – known as arrhyth...

RESEARCH
Understanding how gene mutations cause arrhythmiaImperial College London | Professor Dr Thomas Brand
When we exercise, increased amounts of adrenaline circulate in our body stimulating the heart to beat faster. Adrenaline works by stimulating another molecule called cyclic AMP (cAMP) which is recognised by protein molecules in heart cells....

RESEARCH
New MRI scans to help guide tests for arrhythmiaImperial College London | Dr Jennifer Keegan
Doctors usually investigate and treat alterations in the heart’s rhythm – known as arrhythmias –using electrophysiology (EP). This involves passing flexible electrodes through a blood vessel and carefully placing them at specific positions ...

Dantrolene and VKII-86 as possible treatments for CPVT and other arrhythmiasUniversity of Manchester | Dr Luigi Venetucci
Calcium is vital for the function of our heart and it is fundamental to the control of our heartbeat. A protein called the ryanodine receptor is crucial in the process; it allows calcium to move to areas in the heart cell where it can be us...

Developing a new, safer method to target ablation for arrhythmiasKing's College London | Dr Martin Bishop
Dr Martin Bishop and his team at King’s College London are developing a new, safer method to help doctors identify areas of heart tissue that cause abnormal heart rhythms, or arrhythmias, so they can receive more accurate ablation therapy. ...

RESEARCH
Tailoring treatments for dangerous abnormal heart rhythmsSwansea University | Professor Christopher George
BHF Professor Alan Williams studies abnormal heart rhythms, or arrhythmias, which can be fatal. Although we understand some of the processes involved in arrhythmias, the efficacy of current treatments are variable, and the causes of abnorma...

Identifying people at risk of arrhythmias after cardiac resynchronisation therapyKing's College London | Dr Steven Niederer
Dr Steven Niederer and his team at King’s College London are working out why some people develop heart rhythm problems, or arrhythmias, after they receive cardiac resynchronisation therapy (CRT). CRT is used to treat heart failure, but it a...

RESEARCH
Do Purkinje fibres have a role in stretch-induced heart rhythm problems?University of Leeds | Professor Edward White
Researchers in the UK and France are testing a new theory that could change the treatment of irregular heart rhythms. Irregular heart rhythms – when the heart beat is too fast, too slow, ‘fluttering’, or chaotic – are called arrhythmias. T...

Developing better tests and treatments for arrhythmias in the upper heartUniversity of Birmingham | Dr Davor Pavlovic
Arrhythmias (fast, slow or irregular heartbeats) most commonly occur in the upper chambers of the heart. Drugs used to treat arrhythmias target sodium-transporting molecules that are present in both upper and lower chambers of the heart. Ho...
