Arrhythmia Research

An arrhythmia (also known as cardiac dysrhythmia) is defined as an irregular heartbeat, and results from abnormal electrical activity in the heart. There are various different types of arrhythmia, often resulting in a heartbeat that is too fast (tachycardia) or too slow (bradycardia). Atrial and ventricular fibrillation, which are the most common cardiac arrhythmias, account for 10-20% of all deaths among adults in the Western world. The incidence of atrial fibrillation increases with age; it not only affects cardiac function, but also increases the risk of stroke and may worsen heart failure.
