Creating a computer model of the heart to better understand atrial fibrillationKing's College London | Dr Steven Niederer
Normally, your heart’s natural pacemaker sends out regular electrical impulses. Atrial fibrillation (AF) is the most common heart rhythm disorder, mainly affecting people over 55. AF happens when the regular electrical impulses in the atria...

Refining ablation methods to treat atrial fibrillationImperial College London | Professor Prapa Kanagaratnam
Atrial fibrillation (AF) is a common heart rhythm disorder that causes palpitations and breathlessness. The condition is caused by abnormal electrical activity originating from the veins that drain into the left atrium. Catheter ablation is...

Does amyloid build-up in the heart make aortic stenosis more difficult to treat?University College London | Professor James Moon
The most common form of heart valve disease is aortic stenosis, where there is narrowing of the aortic valve – the valve that controls blood flow from the heart into the main blood vessel supplying the body. The heart has to pump harder to...
